Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.what on earth is going on here
Ummm no i don't think so
oh
no they're not the same
uh
first one is stretching one end of the spring with a box with velocity v
wait
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
wait uh so what will be the gain in pe
in the 2nd case
ah shi im stupid its one spring
if the displacement on one end is x, then 1/2 K (2x)^2
i think
someone confirm that
basically ths question but i did 2(1/2) K x^2 💀 :slu
@Nimboi In these cases K = 0.5μ (v_rel)² right?
I've forgotten mechanics 💀
i suck at mechanics too dw
reduced mass from where?
original equation is just 1/2 k x^2
there's no mass term
no reduced mass
no mass
damn i was like i aint gonna revise mechanics questions
now i gotta
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?
ooh righ ive done some ques like that
block's kinetic energy = spring's potential energy
wow i forgot
Bhai, my teacher last year didn't teach us FBDs. I learnt them like two months ago in revision time.
solving for x here gives you the max compression by the block
wtf
how did you pass 11th
Ratta.
wait wasnt there like a specific concept for max compression
ouch
why are good physics teachers rare
Physics, Chem, Maths mein 100/100
In 11th exam
was there? i thought it was just energy conservation
through raw ratta?
English - 91
Sanskrit - 99
CS - 95
i mean not maths but
still
Maths bhi ratta
holy
wtfbro
They give the actual numbers beforehand.
wHAT
Yeah, it's that predictable
what cbse school are you affiliated with 💀
Papers repeat every six years or so
Not CBSE
State
i can confirm u can do neet questions without fbd because i also didnt know fbd properly until couple of months ago
sorry yeah but wtf
nahh
Eleventh papers are also board btw
Board is just crappy
state is completely violating
omg
this is just sadge
Apparently two years ago, board have 25 marks grace
*gave
In chem
nigga ðŸ˜
oh my god
this country bro
and it counts in cert
cet*
still?
50% ?
Because they gave like two CET/JEE questions, and then the teachers rioted
Yup
what level of abomination
;-;
Karnataka aajao.
im from bangalore
just in cbse
Oh wow
Didn't know that
yall have it wild
Wait which institute?
DPS east
+ allen HSR
O H
for a second i thought "should i leak my school and coaching?" and then remembered that flower straight up just pasted his address in chat
Wait a sec I have friends from DPS. As in, formerly DPS
Dw dw
I'll tell my institute in DMs
