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 alpha 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 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 body with zero initial velocity slips from the top of an inclined plane forming an angle alpha with the horizontal. The coefficient of friction mu between the body and the plane increases with the distance s from the top according to the law mu = bs . After what distance the body will stop.

A ball is projected with velocity u at right angle to the slope which inclined at an angle alpha with the horizontal. The distance x along the inclined plane that it will travell before again striking the slope is-

A smooth inclined plane is inclined at an angle theta with the horizontal. A body starts from rest and slides down the inclined surface. The time taken by the body to reach the bottom is

A ball is projected horizontally with a speed u from the top of inclined plane of inclination alpha with horizontal. At what distance along the plane, the ball will strike the plane ?

A disc of mass m slides with the zero initial velocity down an inclined plane of inclination theta to the harizontal, having traveled the distance d along the horizontal plane, the disc stops. Find the work performed by the friction over the whole distance, assuming the friction coefficient mu for both the inclined and horizontal planes.
