A solid, uniform ball rolls without slipping up a hill, as shown in the figure. At the top of the hill, it is moving horizontally; then it goes over the vertical cliff. Take V= 25.0 m/s and h = 25.0 m.
a.) How far from the foot of the cliff does the ball land?
b.) How fast is it moving just before it lands?
