A ball collides with an inclined plane of inclination `theta` after falling through a distance h. if it moves horizontal just after the impact, the coefficient of restitution is

A ball after falling a distance collides an inclined plane of inclination theta . If after the collision , the ball moves horizontally , find the coefficient of restitution.

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

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

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

After falling from a height h and striking the ground twice, a ball rise up to the height [e = coefficient of restitution]

A ball is dropped on a smooth inclined plane and is observed to move horizontally after the impact. The coefficient of restitution between the plane and ball is e. The inclination of the plane is

A ball is dropped on a smooth inclined plane and is observed to move horizontally after the impact. The coefficient of restitution between the plane and ball is e. The inclination of the plane is

A 1 kg ball moving at 12 m//s collides head on with a 2g ball moving in the opposite direction at 24 m//s . The velocity of each ball after the impact, if the coefficient of restitution is 2//3 is
