Question

A boat with a horizontal tow rope pulls a water skier. She skis off to the side so that the rope makes an angle of 10 degrees with the forward direction of motion. If the tension in the room is 200 N, how much work does the rope do on the skier during a forward displacement of 100 m?

1 Answer

  • Answer:

    19696 J or 19700 J

    Explanation:

    COMPONENT OF FORCE IN DIRECTION OF DISPLACEMENT IS

    F cosФ = 200 cos 10° = 196.96 N

    work = component of force in direction of displacement ×  displacement

            = 196.96 × 100

            = 19696 J

           = 19700 J
