The rotor of an electric motor has an angular velocity of 3600 rpm when the load and power are cut off. the 125-lb rotor, which has a centroidal radius of gyration of 9 in., then coasts to rest. knowing that kinetic friction results in a couple of magnitude 2.5 lb¡ft exerted on the rotor, determine the number of revolutions that the rotor executes before coming to rest. (round the final answer to its nearest whole number.)
