A particles falls through a verticle height `h` and makes perfectly elsatic impact with a smooth inclined plane of angle `alpha`. The time interval between its first and second impact on the incline

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 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 starts falling with zero initial velocity on a smooth inclined plane forming an angle a with the horizontal. Having fallen the 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 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
