A ball starts falling freely from a height h from a point on the inclined plane forming an angle `alpha` with the horizontal as shown. After collision with the incline it rebounds elastically off the plane. Then it again strikes the incline at

A ball starts falling with zero initial velocity on to a smooth inclined plane forming an angle alpha with the horizontal. Having fallen a distance h, the ball rebounds elastically off the inclined plane. At what distance from the impact point will the ball rebound for the second time ?

A ball falls freely form a height onto and smooth inclined plane forming an angle a with the horizontal. Find the ratio of the distance between the points at which the jumping ball strikes the inclined plane. Assume the impacts to be elastic.

A ball falls from height h over an inclined plane of inclination 30^@ as shown. After the collision, the ball moves horizontally, the coefficient of restitution is
