Note for OP
+solved @user to close the thread when your doubt is solved. Mention the user who helped you solve the doubt. This will be added to their stats.i can tell you what to do here
1. angular impulse
2.momentum conservation (of disc inside the plane and ball coming back)
btw what did you first think you had to do here like your first thought/idea?
ah angular impulse never thought about that
only momentum conservation i didn't know what to do after that
I guess there is a problem somewhere in question becoz the velocity of mass and the disc itself both are in the same plane....if the velocity would not be in plane we would take the impulse due to normal reaction J=∆P i.e change in momentum in perpendicular direction and then we know Frictional force=uN....so frictional impulse would be uNdt...i.e u(∆P) in perpendicular direction..now u got the Frictional impulse u multiply with R/2 to get angular impulse and then angular impulse=change in angular momentum u find the velocity of disc....
Please correct me if my concepts are wrong about frictional impulse
Great input Sukritya!
@Nikey we good?
