A grinding wheel is in the form of a uniform solid disk of radius 7.00 cm and mass 2.00 kg. It starts from rest and accelerates uniformly under the action of constant torque of 0.600 N-m that the motor exerts on the wheel. (a) How long does the wheel take to reach its final operating speed of 1200 rev/min. (b) Through how many revolutions does it turn while accelerating?
