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 of the constant torque of 0.600 N-m that the motor exerts on the wheel.
(a) How long does it take to reach its final operating speed of 1200 rev/min?
(b) Through how many revolutions does it turn while accelerating?
