1.	A small metal ball falls vertically and strickes a smooth plane inclined at an angle theta to the horizontal (theta lt 45^(@)). The ball rebounds horizontally. Show that a fraction (l-e) of the kinetic energy is lost during the impact and that if m is the mass and mu the speed of the ball before impact, the impulse on the plane is mu sec theta. Here e isi the coefficient of restitutuon.
