M.11.2 Loop the Loop

A ball is rolled down an inclined track which has a vertical 360° loop at the bottom. The rolling ball stays on the track if started from the proper height on the incline. Friction and the rotational energy of rolling must be taken into account. Note that the ball does not roll on its bottom, so it uses even more rotational energy than a rolling sphere.
