Question

A ball of mass 1 kg and radius 10 cm is given an angular velocity 100 rad s and is then dropped from a height H 500 m from a point A above the ground The coefficient of restitution for the collision between the ball and the floor is 0 5 and coefficient of friction between the ball and the floor is 1 3 There is a smooth wall at a distance of 250 m from point O which is vertically below A The collision between the ball and wall is perfectly elastic Find the height at which the ball hits the wall Height of a ball expressed in power of 10 m is H 500 m A 0 B
