a grinding wheel in the form of a uniform solid disk having a radius of 7 cm and a mass of 2 kg. it starts from rest and accelerates uniformly under the action of the constant torque of .600 Nm hat the motor exerts on the wheel. how long does the wheel take to reach its final rotational speed of 1200 rev/min? through how many revolutions does it turn while accelerating?
