A person is making homemade ice cream. She exerts a force of magnitude 17 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 2.0 s, what is the average power being expended?

The work done every 2 seconds is
W = 2 pi R * F = 6.28*0.28*17 Joules

Divide that by 2 seconds for the power in Watts.
