A real A&P test question:
A mechanic wants to put a barrel of used SkyDrol, weighing 120 pounds, into a 1998 Chevy 3/4 ton pickup. The tailgate is 3 ft off the hangar floor and 54" wide. He finds a board 9 ft long to use as a ramp. How much force, in pounds, will be required to push the barrel up the ramp?
