A grinding wheel of radius 0.36 m, which starts from rest, rotates at 1850 revolutions per minute (RPM) and has a moment of inertia of 600 kg m2.

a. What is the angular momentum of the grinding wheel?

b. If torque (T) is defined as the change in angular momentum divided by time, how much torque is required to stop the grinding wheel in four seconds? In one second?

c. Discuss the meaning of the law of conservation of angular momentum. Your response should include the following at a minimum: How is angular momentum affected by changes to the radius of the circle or the speed of the object? How does torque affect angular momentum? What is the linear momentum equivalent of torque?
