Shown here is top view of a table. A particle of mass m is directed towards a disc of radius R and mass m. Mass of both disc and object are m. Velocity of particle before collision is v. Particle moves at a constant distance R/2 above centre as shown. Find final velocities of particle and disc after collision if disc is at rest before collision. (2-dimensional collision)

velocity components along line of impact changes and perpendicular to it remain the same.

thr4 disc now moves with velocity of disc is vsin@ and particl is vcos@ whr sin@=r/2r=1
