A solid ball of radius 0.2 m and mass 1 kg is given an instantaneous impulse of 50 N-s at point P as shown. Find the number of rotations made by the ball about its diameter before hitting the ground. The ball is kept on smooth surface intially

A 2 kg ball is dropped from a height of 1. Find its kinetic energy just before hitting ground.

A ball of mass 10kg hits a smooth horizontal surface with a speed of 10sqrt(2) m/s at angular of 45^(@) as shown in the figure. The coefficient of resitution between the ball and the surface in 0.5 and the ball remains in contact with the surface for 0.1 sec. vecF is the instantaneous force extracted by the ball at any time t duringthe collison.
