Determination of average power spent in turning a crank handle about a fixed axis.
A person is making homemade ice cream. She exerts the force of magnitude 22N on the free end of the crank handle, and this end moves in the circular path of radius 0.28m. The force is always applied parallel to the motion of the handle. If the handles is turned once every 1.30s, what is an average power being expended?
