A water skier, moving at a speed of 8.61 m/s, is being pulled by a tow rope that makes an angle of 34.9 ° with respect to the velocity of the boat. The tow rope is parallel to the water. The skier is moving in the same direction as the boat. If the tension in the tow rope is 137 N, determine the work that it does in 14.9 s.
