A grinding wheel is in the form of a uniform solid disk ofradius 6.96 cm and mass 2.05 kg. It starts from rest andaccelerates uniformly under the action of the constant torque of0.606 N · m that the motor exerts on the wheel.
(a) How long does the wheel take to reach its final operatingspeed of 1 190 rev/min?
  s
(b) Through how many revolutions does it turn whileaccelerating?
rev
