1. (17.2) The rotor of an electric motor has an angular velocity of 3600 rpm when the load and power are cut off. The 110-lb rotor, which has a centroidal radius of gyration of 9 in., then coasts to rest. Knowing that the kinetic friction of the rotor produces a couple with a magnitude of 2.5 lb-ft, determine the number of revolutions that the rotor executes before coming to rest. Notes: The work done by friction is negative. You may convert all units to SI system if you have difficulty in dealing with the English system of measurement.
