A block is initially at rest at the bottom of a ramp. A student pulls the block along the ramp to the top of the ramp using a string. Frictional forces are negligible. The student measures the mass of the block and the speed of the block at the top of the ramp. Which of the following lists the fewest additional measurements required to estimate the total work done on the block as it moves from the bottom of the ramp to the top of the ramp?
