Question

A block of mass 70kg is dragged up a frictionless slope for 15m.  The slope has an angle of 20 degrees above the horizon. Without necessarily solving for the work done on the block, describe this situation physically. Tell me, what forces are at play and how they act. In what direction? What physics principals will you need? What trigonometric principals will you need and what do those principals mean? Demonstrate your knowledge of Work and Energy in your description. Solving the problem will help, but is not required for full credit.
