19. We wrap a light, non-stretching cable around a solid cylinder of mass $50 kg$ and diameter $0.120 m$ , which rotates in frictionless bearings about a stationary horizontal axis. We pull the free end of the cable with a constant $9.0 N$ force for a distance of $2.0 m$ ; it turns the cylinder as it unwinds without slipping. The cylinder is initially at rest. Find angular speed and the final speed of the cable.
