a toy wagon is pulled by exerting a force of 15 pounds on a handle that makes a 30 degree angle with the horizontal. find the work done in pulling the wagon 50 feet.

    We want the force in the direction of motion
    F = 15 cos 30
    then work = force times the distance the force acts
    = 50 * 15 cos 3
    in foot pounds
