A ball moving vertically downward with a speed of 10 m/s collides with a platform. The platform moves with a velocity of 5m/s in downward direction. If e = 0.8, find the speed (in m/s ) of the ball just after collision. A ball moving vertically downward with a speed of 10 m/s collides with a platform.
