10. Conservation of Energy / Energy with Non-Conservative Forces / Problem 11

A block placed at the top of a ball of radius R slides down its surface from rest. In the presence of friction, does the block fly off at a greater angle than if there is no friction? Assume that the mass of the block is M.
