A ball is projected form a point A on a smooth inclined plane which makes an angle a to the horizontal. The velocity of projection makes an angle theta with the plane upwards. If on the second bounce the ball is moving perpendicular to the plane, find e in terms of alpha and theta . Here e is the coefficient of restitution between the ball and the plane.

For perfectly inelastic collision cofficient of restitution e is
