A solid, cylindrical grinding wheel has mass 2.37 kg and diameter 11.0 cm. It has an angular speed of 1224 rev/min. when the motor that turns it is shut off. The wheel slows uniformly to a stop after 48 seconds due to frictional forces.

Find:

a. angular accleleration

b. number of revolutions during the 48 seconds

c. frictional torque that caused the wheel to slow to a stop

d. wheels initial kinetic energy

e. frictional power
