A ball falls vertically for 2 seconds and hits a plane inclined at `30^(@)` to horizon. If the coefficient of restitution is `3/4,` find the time that elapses before it again hits the plane :

A ball (initially at rest) falls vertically for 2 s and hits a smooth plane inclined at 30^(@) to the horizontal. The coefficient of restitution is (5)/(8) . The distance along the plane between the first and second impact of the ball is

A ball is projected from a point in a horizontal plane with a velocity of 20 m/s at 30^(@) with the horizontal. Coefficient of restitution is 0.8, then

A ball after freely falling from a height of 4.9m strikes a horizontal plane. If the coefficient of restitution is 3/4 , the ball will strike second time with the plane after

A ball falls from a height of 10m on to a horizontal plane. If the coefficient of restitution is 0.4 , then the velocity with which it rebounds from the plane after second collision is

A ball falls from a height of 5m on to a horizontal plane.If the coefficient of restitution is 0.4, the height to which it rebounds after 2 collisions is approximately
