A grinding wheel is in the form of a uniform solid disk of radius 7.10 cm and mass 2.02 kg. It starts from rest and accelerates uniformly under the action of the constant torque of 0.608 N·m that the motor exerts on the wheel.
(a) How long does the wheel take to reach its final operating speed of 1190 rev/min? (answer is in seconds)
(b) Through how many revolutions does it turn while accelerating? (answer in revolutions)
