The flywheel of an old steam engine is a solid homogeneous metal disk of mass M = 117 kgand radius R = 80 cm.The engine rotates the wheel at 540 rpm. In an emergency, to bring the engine to a stop, the flywheel is disengaged from the engine and a brake pad is applied at the edge to provide a radially inward force F = 130 N. If the coefficient of kinetic friction between the pad and the flywheel is µk = 0.2,how many revolutions does the flywheel make before coming to rest?

How long does it take for the flywheel to come to rest?

Calculate the work done by the torque during this time.
