A solid disk is rotating clockwise with an angular velocity of ? = 3 rad/s.

(a) Where and in what direction should you apply a force to slow the disk as fast as possible? Draw a picture and describe your answer.

(b) If you apply, a torque of ? = 24 N/m for 10 seconds the disk will stop. Find the moment of inertia of the disk.
