A ball strickes a horizontal floor at 45^(@). 25% of its kinetic energy is lost in collision. Find the coefficient of restitution.

A ball strickes a horizontal floor at an angle theta = 45^@ with the normal to floor. The coefficient of restitution between the ball and the floor is e = 1//2 . The function of its kinetic energy lost in the collision is.

A ball strickes a horizontal floor at an angle theta = 45^@ with the normal to floor. The coefficient of restitution between the ball and the floor is e = 1//2 . The fraction of its kinetic energy lost in the collision is.

A ball strickes a horizontal floor at an angle theta = 45^@ with the normal to floor. The coefficient of restitution between the ball and the floor is e = 1//2 . The fraction of its kinetic energy lost in the collision is.

A ball stikes a horizontal floor at an angle theta = 30° with normal to the floor . The coefficient of restitution between the ball and floor is. e = 1/3 . The percentage of its kinetic energy lost in the collision is nearly

Is whole of the kinetic energy lost in a perfectly inelastic collision ?
