A water skier, moving at a speed of 6.42 m/s, is being pulled by a tow rope that makes an angle of 39.7 ° with respect to the velocity of the boat (see the drawing). 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 131 N, determine the work that it does in 13.1 s.

Work=tension*distance*sinTheta
there theta is the angle between tension adn the displacement vector (39.7deg)

distance=velocity*time

ARRRRGGGGG. Work=tension*distance*COSINETheta

sorry about that.
