A ball moves towards a smooth wedge with a velocity `mu` as shown in figure `-4.145.` After colllision the ball rebounds verically upwards. The coefficient of restitution is e. Find the velocity of the wedgt block and bell after collision. Do you need some other parameters to solve the given problems.

Answer

`"["v_(block)="mu"/M,v_(ball)=utantheta(e-(m)/(M))` or u `costheta` where m and M are the masses of ball and block."]"
