The rotor of an electric motor has an angular velocity of 3570 rpm when the load and power are cut off. The 65-kg rotor, which has a centroidal radius of gyration of 175mm, until it reaches the maximum speed of 5250 rpm. Knowing that the kinetic friction results in a couple of magnitude 4.5 N.m exerted on the rotor, determine the number of revolutions that the rotor executes, before achieving its maximum speed and the time it took. (The final answer should be in two decimal places with correct units)

A 1.6-kg tube AB can slide freely on rod DE which in turn can rotate freely in a horizontal plane. Initially the assembly is rotating with an angular velocity of magnitude w = 5 rad/s and the tube is held in position by a cord. The moment of inertia of the rod and bracket about the vertical axis of rotation is 0.30 kg.m2 and the centroidal moment of inertia of the tube about a vertical axis is 0.0025 kg.m2If the cord suddenly breaks, determine (a) the angular velocity of the assembly after the tube has moved to end E, (b) the energy lost during the plastic impact at E.
