A For one impact, the speed at which the ball hits the surface equals the speed at which it leaves the surface. B The ball rises and falls through the same distance between impacts. C The acceleration of the ball is the same during its upward and downward motion. D The speed at which the ball leaves the surface after an impact is equal to the speed at which it returns to
