2) A 3.00 kg uniform silver disk made from an alloy of copper and zinc is attached to the center of a motor made by Honda. Assume the radius of the disk to be 22.0 cm. The motor exerts a constant torque of 1.00 Nm which accelerates the disk uniformly from rest. a) What is the time required for the disk to reach an angular speed of 8.00 x 102 rpm? b) What is the number of revolutions through which the disk spins before reaching this angular speed?
