solid uniform ball rolls without slipping up a hill of height 28.0 m that ends in a vertical cliff. The ball is initially moving at 25.0 m/s. When the ball reaches the top of the hill it is moving horizontally and goes over the cliff landing on level ground the same height as the foot of the hill. (a) How far from the face of the cliff will the ball land and how fast is it moving just before it strikes the ground? (b) Explain why the final speed just before it hits the ground is greater than its initial speed of 25 m/s
