1.	A ball of mass m collides with the ground at an angle a with the vertical If the collision lasts for time t, the average force exerted by the ground on the ball is : (e= coefficient of restitution between the ball and the ground)
Answer» SOLUTION : `therefore` `Ft = m (eu cos ALPHA + u cos alpha) (or) F = ( m u cos alpha (1 + E ))/( t)`
