mechanics
i hve solved the que it was pretty simple. but where did the vertical velocity just before collision? theyt havent mentioned anything about that so i took it zero cause obv there can't be any vertical velocity upon collison but still whats the logic?

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.in the solution they have written '' where did the vertical velocity go?' and left me with the question:aah:
@hardcoreisdead :uhh:
revise toh nahi kia hai but ill try
vertical velocity would give the ball B a downward impulse ig
which the string would handle
na vertical velocity ka impulse laga to string break ho jyega
Equilibrium condition me hai ball
thats the neat part
it doesnt
Bro picking up phrases 🗣️
😭
:aah:
Fir kaha gyi velocity
Air friction wgera to kuch hai nai
arey
rope ko impulse d
upar hinge hai uske upar force laga
aur usi pe dissipate ho gya
try imagining the situation irl
(also tell yeh kaise kia com revise nahi kia hua)
Mhm ye ho skta hai cause or koi reason to dikh ni raha
Arey kuch nahi momentum conserve krdia x me
Velocity aagyi
Usko root 5gr se equate kara
Or d ke lie wo range ka concept lagaya
monkey jis velocity se jump karega ball A se usi se ball B pe jayega
and same hi angle pe
right?
uss se d= 10L ??
Ha Ux velocity se
ans yaad nahi h yr dekhna pdega
let ux be the velocity of monkey in x axis
mux = 2mVa
with the same velocity ux it reaches B sticks to it and monkey + ball system execute circular motion with velocity v = root(5gL)
mux = 3mv
d= 90L
2nd part ka ans batana
Yup d=90L
Impulse = m(root(45gl))
$mu_y$
Real potato
dont close mereko dekhna ye question
revision hojayegi
tum shi keh rhe the wo impulse hinge samhlega @hardcoreisdead
Tabhi tension ka impulse ye ayega
Chill nhi kruga close aarm se try kro
thanks man
uy= ux = 3root5gl
hmm alr
why not 2m btw
2m mass pe velocity uy daalega monkey
Impulse = change in momentum
Final momentum zero hogya na
Y direction me
Initial mu_y tha
Samjha?
but x axis mein bhi toh A ki velocity hai
X ki velocity se string ka tension change nai hoga dt time me
Y ki velocity se hoga
