A string is wrapped several times around a solid cylinder of mass m and radius r, which rotates about a stationary horizontal axis. The free end of the spring is pulled by constant force F. The cylinder rotates without slipping. the cylinder is initially at rest. Find the angular speed of the cylinder and the speed of the cable when the free end of the cable has been pulled out by a length s.
