Concept

Problem: A ramp is inclined at 36.9° above the horizontal. A block with mass 0.500 kg is pulled up the ramp by a force F.  The block starts at point  A at the bottom of the ramp and ends up at point B at the top of the ramp. The distance from  A to B, measured along the ramp is 5.00 m. The work done on the block by gravity as the block moves from point A to point B is A) +24.5 J B) -24.5 J C) +19.6 J D) -19.6 J E) +14.7 J F) -14.7 J G) None of the above answers
