A solid, uniform ball rolls without slipping up a hill. 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 = 30.0 m . Part A: How far from the foot of the cliff does the ball land? Part B: How fast is it moving just before it lands? Part C: Notice that when the ball lands, it has a larger translational speed than it had at the bottom of the hill. Does this mean that the ball somehow gained energy by going up the hill? Explain!

1) A solid ball of mass M and radius R rolls without slipping down a hill with slope tan θ. (That is θ is the angle of the hill relative to the horizontal direction.) What is the static frictional force acting on it? It is possible to solve this question in a fairly simple way using two ingredients: a) As derived in the worksheet when an object of moment of inertia I, mass M and radius R starts at rest...
