A fisherman starts his outboard motor by pulling on a rope wrapped around the outer rim of a flywheel (A flywheel is a rather heavy disk of metal ) The flywheel is a solid cylinder with a mass of 9.5 kg and a diameter of 15 cm. The flywheel starts from rest and after 12 s, it rotates at 51 rad/s.
What torque does the fisherman apply to the flywheel ?
