Opt•3mo ago
Ummm no i don't think so
Nimboi
Nimboi•3mo ago
oh no they're not the same
simplybear

uh

first one is stretching one end of the spring with a box with velocity v
simplybear
simplybearOP•3mo ago
wait
Nimboi
Nimboi•3mo ago
second one is stretching two ends of the spring with 2 boxes with velocity v spring is stretched twice as much in the second one
simplybear
simplybearOP•3mo ago
wait uh so what will be the gain in pe in the 2nd case ah shi im stupid its one spring
Nimboi
Nimboi•3mo ago
if the displacement on one end is x, then 1/2 K (2x)^2 i think someone confirm that
simplybear
simplybearOP•3mo ago
basically ths question but i did 2(1/2) K x^2 💀 :slu

Opt•3mo ago
@Nimboi In these cases K = 0.5μ (v_rel)² right? I've forgotten mechanics 💀
Nimboi
Nimboi•3mo ago
i suck at mechanics too dw reduced mass from where? original equation is just 1/2 k x^2 there's no mass term
simplybear
simplybearOP•3mo ago
no reduced mass no mass damn i was like i aint gonna revise mechanics questions now i gotta
Nimboi
Nimboi•3mo ago
mechanics is a slippery thing

What about those questions where they have a block coming in, hitting a block-spring system? They ask maximum compression na?
simplybear
simplybearOP•3mo ago
ooh righ ive done some ques like that
Nimboi
Nimboi•3mo ago
block's kinetic energy = spring's potential energy
simplybear
simplybearOP•3mo ago
wow i forgot
Opt
Opt•3mo ago
Bhai, my teacher last year didn't teach us FBDs. I learnt them like two months ago in revision time.
Nimboi
Nimboi•3mo ago
solving for x here gives you the max compression by the block wtf how did you pass 11th
Opt
Opt•3mo ago
Ratta.
simplybear
simplybearOP•3mo ago
wait wasnt there like a specific concept for max compression
Nimboi
Nimboi•3mo ago
ouch why are good physics teachers rare
Opt
Opt•3mo ago
Physics, Chem, Maths mein 100/100 In 11th exam
Nimboi
Nimboi•3mo ago
was there? i thought it was just energy conservation through raw ratta?

i mean not maths but still
Opt
Opt•3mo ago
Maths bhi ratta

i can confirm u can do neet questions without fbd because i also didnt know fbd properly until couple of months ago
Nimboi
Nimboi•3mo ago
sorry yeah but wtf nahh
Opt
Opt•3mo ago
Eleventh papers are also board btw Board is just crappy
Nimboi
Nimboi•3mo ago
state is completely violating omg this is just sadge

and it counts in cert cet* still? 50% ?
Opt
Opt•3mo ago
Because they gave like two CET/JEE questions, and then the teachers rioted Yup
