Task id16816

Solve Problem 12.7 under the assumption that a ball of mass m and radius r rolls down from the top without slipping. Neglect energy loss due to rolling friction. 12.7. At the highest point of a ball of radius R, lies a small puck of mass m. After a slight push, the puck begins to slide off. Find the force of pressure of the puck on the ball as a function of the angle between the radius vector and the vertical. Where will the puck leave the ball? Ignore friction.
