Time from a, r, and ω [Ex. 1]

A car decelerates at 6.6 m/s². The tires have a radius of 0.26 m and have a positive direction during the forward motion. If the initial angular velocity is 94 rad/s, how long does it take the car to fully stop?

-- Given values: -> a = 6.6 m/s² -> r = 0.26 m -> ωi = 94 rad/s -> ωf = 0 rad/s

-- Use one of the kinematic equations 1. ωf = ωi + αt 2. Δθ = ωit + (1/2)αt² 3. ωf² = ωi² + 2αΔθ

-- Use Equation 1

-- Missing α, which is angular acceleration

-- Solve for α

α = a/r α = 6.6 / 0.26 α = 25.385 rad/s²

-- Should be negative, because the car is decelerating

α = -25.385 rad/s²

-- Now solve for t using Equation 1

ωf = ωi + α 0 = 94 + (-25.385)t 0 = 94 - 25.385t -94 = -25.385t 94 = 25.385t 94 / 25.385 = t 3.7 = t

-- It takes the car 3.7 seconds to stop

DO YOU WANNA HELP YOUR DISABLED NEIGHBORS?

Rake up the wet leaves before we eat shit on the sidewalk! Your city or town should be doing it, but why would they??

I simply think this fandom doesn't give Wei Wuxian enough credit for the various ways in which he saved Lan Wangji

#mdzs #mo dao zu shi #wangxian #idk man- i just see a lot of “Lan Wangji has always been protecting Wei Wuxian” posts and its like...#I mean... Lan Wangji has always certainly been trying to protect Wei Wuxian #it took him a long time to figure how to successfully do that though #rereading the books rn and noticing theres a lot of instances that could be read as lwj being frustrated over his inability to protect wwx #like he seemed ready to cry when wwx went missing for a while and then came back with the cursed leg #lwj has always been great at protecting wwx from physical threats (ex: waterborn abyss) but had no idea how to protect him from himself #meanwhile wwx has always been instictually good at saving lwj from both #like I'm 100% lwj would've become like Jiang Cheng if wwx hadn't snapped him out of the blindly following authority thing #and also like... 15 y/o lwj wasnt happy with his life. he was lonely and stressed and literally signing up to be flogged whenever he goofed #wwx is who allowed lwj to grow up by showing him what it was like to actually be a kid (shown in story whenever lwj gets drunk)#he led lwj to having a more flexible mindset. and it both let lwj relax and set lwj up to be a better parent #looking into lwj's dynamic with the juniors- he lets them break a fuck ton of the petty rules and encourages them to question authority #he also teaches them to not be married to any one meathod of problem solving #wwx is also able to save lwj from his own stubbornness #ex: carrying lwj when he broke his leg. getting lwj to cough up bad blood. getting lwj to keep the rabbits #wwx also tends to give lwj the words he has trouble saying himself. helps him communicate #wwx also protects lwj in fights a lot but thats narratively less important #except the various times wwx puts himself in danger to help lwj. those times are what made it so lwj could never move on from wwx #like with the cave incident #or when wwx helped surpress the arm instead of using the chaos to escape cloud recesses #tldr i guess: i think this fandom tends to treat lwj being the best like its natural to him when really wwx accidentaly rewired his brain #I'm looking directly at fanfic writers who act like the Lans would've treated wwx better than the Jiangs #lwj had to do so much work and self reflection post meeting wwx to be the way he is. he is not the sole product of the Lan teachings

Why does Ren have 4 ears? Are they all real or is one set fake?

Hehe I’ve gotten this question a lot actually! They’re all real— I like to think hybridization isn’t always a clean balance of traits, so Ren just unfortunately ended up with two sets of ears— his Dog ears being much more receptive to sound, naturally— and sometimes when the extra intake of sound is too overwhelming, I imagine he wears earplugs in his human ears to help adjust :> it’s a bit weird, but idk! i like to make designs funky and nonconventional! I liked the idea that Ren had hearing struggles due to wonky hybridization and just kept the concept :>

#dbhc #dbhc ask #ask #anon #dbhc ren #renthedog #dbhc doc #since I talk about him in the tags FGBJCGHN #it’s another one of those situations where I drew it that way when I was younger because I didn’t really understand why ppl were drawing #hybrids with flat spaces where human ears should go and have dog ears on the top of the head— I couldn’t figure out anatomically #it makes more sense to me now since animals are literally like that but it’s just something I kept doing and came up with a better #reason for it later once I had a better understanding of stuff #I don’t necessarily think two sets of ears is logically more sound than reworking the anatomy of a human head to have ears on top but!#it’s really not that deep LMAO #I like the idea of hybridizations being wonky because weird stuff physically happens to people all the time #hybrid or not #and then we gotta deal with the physical consequences of stuff we were born with… yknow #ANYWAY WHAT A WEIRD RAMBLE #tldr funky hybrid who now has hearing problems/gets overwhelmed easily by sound. ren the dog I love you #and if you were to look into my soul you would find that I also think dbhc doc helped him craft earbuds using android tech to work perfectly #to tune out the sounds he needs #:3 because they are friends and I think doc should use his expertise to help make life easier for ren #I’M STILL RAMBLING!!!#good grief

i love how sometimes, despite all the medical advancements of the 21st century, the only thing that relieves pain is sitting/laying/standing in a weird position because it places/doesn't place pressure on certain spots

Acceleration and Force [Ex. 1]

A 100 kg boat has a propeller that applies a 600 N force to the boat while the water applies a 200 N resistance to the boat's motion. What is the acceleration of the boat?

-- use Newton's second law

F = m ∗ a

-- motion is only occuring in the x-direction

F(net,x) = m ∗ ax

-- expand F(net,x) with the given values

600 - 200 = m ∗ ax 400 = m ∗ ax

-- m is given as 100 kg

400 = m ∗ ax 400 = 100 ∗ ax 400 / 100 = ax 4 / 1 = ax 4 = ax

-- the acceleration is 4 m/s²

Margo/Sergei AU: There has, and will always be, a huge rivalry between Apollo State and Soyuz University. Whether it's football or physics, the rivalry is intense and every student knows where their loyalty should belong. But after a joint project brings Margo Madison and Sergei Nikulov into each other's orbit, school loyalty doesn't seem as important as working the problem together.

#margo x sergei #for all mankind #dd: edits #ship: margo x sergei #tv: for all mankind #margo x sergei au #sergei is definitely stripped naked and left on the football field and margo definitely finds him and brings him back to her dorm #and they drive a little out of town to go to a diner to eat burgers and work on physics problems

I did a drawing :3

(^ scan ^)

I’m actually really proud of it! I don’t usually use this style bc it’s hard but I like it a lot^^

I wanna work out and get stronger, it would help with some of my disability symptoms. The ironic bit is that if my condition is what doctors think it is that means I'll struggle to build muscle. And even barring that, my fatigue and my pain make it difficult to walk around campus let alone go home and work out.

My physically abled gymbro friend told me to just do a little every day, and I know he means well but I don't have the energy to get dressed or brush my teeth most days.

THE GLASSES ARE BACK!

#precious boy #this is the kind of little character-building details that i appreciate #the fact that lupin occasionally needs glasses to read or work on tiny things #for all his incredible physical abilities he's still human with limitations and parts of his body that don't work #(that and jigen's ongoing tooth problems lmao)#lupin iii #teal jacket

The gag is Zoro and Shanks aren’t that different. Zoro is also completely reckless with his body less so now but I have no doubt that even now if he needed to cut off any part of his body to win, to save his crew he would do it without hesitation just like shanks.

And the thing is Mihawk would still fight him as long as Zoro can pick up a sword Mihawk would still fight him and relish in it.

Zoro loses an eye, Mihawk still trains him.

And Shanks…..Shanks loses his mind a little bit

#the spiritual continuation on my other Shanks is jealous of Zoro piece #but yeah I think on some level shanks still hasn’t completely gotten that left arm gate was about everybody but the actual arm #it was about Mihawk having always known that they didn’t have the same goals but pretending anyway until he physically can’t #but even if Zoro was just a floating disembodied head he’d still pick up a sword in his mouth and want to be the best #and that is something mihawk can work with #shanks then fucks mihawk hard that night because he’s the only one that gets this this is something zoro can’t take #but jokes on him Zoro has already wiped the good ole memory banks clean cause that’s his dad and he would die before acknowledging the very #obvious sex noises #I can just see shanks watching their training session and his eye is twitching.#lol from that moment on anytime anyone brings up zoro or his progress shanks’ eye twitches it’s starting to become a problem #just shanks and his completely one sided beef with his sons best friend and boyfriends son #one piece #throwing thoughts to the void #dracule mihawk #hawkeye mihawk #op #mishanks #akagami no shanks #shanks #red haired shanks #akataka #roronoa zoro #zoro #mihawk x shanks #one piece meta #one piece analysis

Alda posted some art and got me thinking about this blog again so here are some cool burners and increasingly unhinged Marginalia Mikes

#Motorcity #Mike Chilton #Julie Kane #Dutch Gordy #Texas (motorcity)#Chuck (motorcity)#Art Is Hard #Life Ruiner #He Scream At Own Car #The Queen #TEXAS!!!#Robot Aesthetic #hey guys??? he's mimk chiltom U_U #does Texas understand what's being explained to him??? no absolutely not lol. is he about to start chopping at the hologram. yes.#but in his defense chuck just said ''the shape isn't a shape it's a concept think about it like a physics problem and work backwards'#which makes sense to him and like four other people in Detroit but is otherwise essentially useless magical nonsense gobbledygook

justin says he doesn't like to be called justin, prefers jets... but ja'marr and joe call him justin plenty.... #intriguing

(look at who liked this post lmao) (i also went back through all the vikings posts about justin's extension/press conference and ja'marr only liked the initial post and this one 😭)

#it's late but know that i have Thoughts about justin how he's outwardly so charismatic and it looks so natural for him at first glance #but then you look a little deeper and how he's so firm with his preference for 'jets' (admits that it's almost like a shield for him)#to the point where he even wanting his teammates to call him that bc that's how he always wants to be seen #but if it's joe or ja'marr? no problem there.#(something something they know justin too well and any walls that justin could put up would do shit against them)#anyways you also have to note that justin's almost always wearing sunglasses #(which is such a symbol - a physical barrier that affects how the world sees justin and how justin wants to be seen)#and he's almost always playing with his hands constantly during interviews and it reminds me so much of what i do when i'm nervous #wringing my hands back and forth bc i don't know what to do with them #in conclusion -justin being forced into the face of the franchise and actually being really really good at it #(insert that post about accidentally becoming important at work bc i actually think that's what happened to justin 💀)#and he tries to cope with it by building another persona who actually does love all of that shit #justin jefferson #both he and ja'marr -so simple on their surface #but they have layers. like an onion.#jjmarr #adjacent at least

I just opened Luke's fandom wiki page to add the new ADHD status, opened Divorces and Teddy Bears to search for the timestamp where Sam and Luke talk about Luke's ADHD, sat through the entirety of the longform, and closed the tab having completely forgotten about the timestamp.

The irony of this entire sequence is hilarious.

#shoot from the hip #and you know what makes this even better?#I was actually supposed to be doing my physics homework this whole time #and I got distracted when I suddenly remembered that they announced luke's ADHD diagnosis #I might be the most ADHD non-ADHD person ever #time to *actually* get back to work now #(does this mean get back to editing the fandom wiki or get back to doing my physics homework? who knows)#(maybe this means continue working on that amigurumi santa claus that I started and forgot about)#(I might have a problem)

i have no mouth and i must scream speech but for about insomnia hate hate hate let me tell you how much i have come to hate being awake

#took half an expired tops brand unisom . wheeeee medicine that does nothing and then the next day you're groggy for twelve hours #but i have to do SOMEthing if i don't Try to make myself sleep that's Giving Up and if you Give Up . well #this is the second week in a row that ive failed to sleep on a night leading into the work week and i know most of the external reasons why #like. busy day tomorrow so anxious. haven't given myself a full weekend in a really long time so strung out.#had important stuff to do earlier that didn't happen so dwelling on that. woke up at 9am and wasn't out of bed until ten thirty so like #i got more than adequate sleep last night but this does not make me feel less worried about NOT sleeping TONIGHT #because again. every time i have a night of big insomnia im convinced that it's the beginning of an unending trend #that will make me wind up like my mother who is lucky she gets more than three hours of sleep every couple of weeks #and while she's done this her whole life qnd has adjusted to it (as much as a body can) i just know. based on how insomnia is for me #that i never could. it would be exactly as terrible every time i would never be able to be calm while it was happening #anyway everybody send me your best knockout gas #AND. it's SNOWING. fuck everything i hate it all #tomorrow im gonna be groggy as hell and have to drive to work and back and have to be With It bc we're doing activities and shit #and have to be like the model of library enthusiasm when i barely have that on a good day. and not actually physically groan #every time someone new wants a card because it means i have to interrupt what im doing dor the next fifteen minutes to say a spiel #i know i shouldn't hate that i should be glad we're getting engagement. and i am. i just wish i wasn't the one at the desk #and im not good at keeping that off of my face or being welcoming when i dont feel welcoming #i haven't gotten to do processing at my actual office desk in months. haven't gotten to be Off The Floor #which certainly hasn't helped my overall stress levels. i need to not be socially on so much it's slowly pulling me apart #and then i get home wnd im too tired to do anything and my house also falls apart around me #but if i DON'T have outings i also rot . there's no solution to this problem. not without quitting my job which ill never do #bc in today's market id never get anything half as good as this ever again. and as has been established. this relatively good job #is still not good enough for me not to be emotionally and mentally falling apart
