Homework Help: Work II

  1. Oct 8, 2007 #1
    1. The problem statement, all variables and given/known data

    A truck with a horizontal tow rope pulls a car. The car skis off to the side, so the rope makes an angle of 15.0degrees with the car's direction of motion, and then continues in a straight line. The tension in the rope is 180 N.

    How much work is done on the car by the rope during a displacement of 300 m?

    2. Relevant equations

    W = F*s
    W = Fscos [tex]\phi[/tex]

    3. The attempt at a solution

    W = 180(300)cos15
    W = 52159.99

    seems to large o_O
