Question

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.

Answer 1

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

Answer 2

thank you..

Answer 3

a 20 kg wagon is pulled along the level ground by a rope inclined at 30 degrees above the horizontal. A friction force of 30 N opposes the motion. How large is the pulling force if the wagon is moving with a constant speed?
