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

thank you..
