Find how many revolutions does it turn while accelerating

Reference no: EM13539416

A grinding wheel is in the form of a uniform solid disk of radius 6.90 cm and mass 1.90 kg. It starts from rest and accelerates uniformly under the action of the constant torque of 0.603 N · m that the motor exerts on the wheel.

(a) How long does the wheel take to reach its final operating speed of 1 120 rev/min?

(b) Through how many revolutions does it turn while accelerating?
