The wheel on a bench grinder has a diameter of 0.3048 m and a mass of 2.4 kg. It is spinning at 26.2 rad/s when the grinder is turned off. It takes 150 seconds for the wheel's angular velocity to drop to 13.1 rad/s.
a.) Calculate the angular acceleration of the wheel.
b.) Calculate the net torque on the wheel.
