A person is making homemade ice cream. She exerts a force of magnitude 22 n on the free end of the crank handle, and this end moves in a circular path of radius 0.28 m. The force is always applied parallel to the motion of the handle. If the handle is turned once every 1.3 s. What is the average power being expended?
