Question:

A water-skier, moving at a speed of 9.30 m/s, is being pulled by a towrope that makes an angle of 37.00 with respect to the velocity of the boat (see the drawing). The towrope is parallel to the water. The skier is moving in the same direction as the boat. If the tension in the towrope is 135 N, determine the work that it does in 12.0s.
