down. The ball starts at the top step with a vertical velocity component of zero. If all the collision with the stairs are elastic, and if the vertical height of the staircase is 3m determine the bounce height when the ball reaches the bottom of the stairs. Neglect air resistnace.
Since the collisions are elastic, no energy is lost.
So the potential energy the ball had when it started at 3m height is still there at the last bounce which is again elastic, so the ball will bounce to 3m height.
