A uniform spherical ball of radius rb is resting inside a circular thin hollow cylinder of radius rc . The cylinder center is then pulled with a constant velocity V as If no slip is permitted between the ball and the cylinder and the cylinder and the floor, what is the minimum required speed V so that the ball can roll completely round the inside surface of the cylinder?
