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

A small ball falling vertically downward with constant velocity 2 m//s strikes elastically an inclined plane moving with velocity 2 m//s as shown in figure. The velocity of rebound of the ball with respect ground is
