An external force ?⃗ moves a 2.50-kg box at a constant speed ? up a frictionless ramp, as shown in the figure. The force acts in a direction parallel to the ramp. Calculate the work ? done on the box by this force as it is pushed up the 5.00-m ramp to a height ℎ=3.00 m. How does the work done on the box compare to the change in gravitational potential energy Δ?grav that the box undergoes as it rises to its final height?

Question

An external force ?⃗ moves a 2.50-kg box at a constant speed ? up a frictionless ramp, as shown in the figure. The force acts in a direction parallel to the ramp.

Calculate the work ? done on the box by this force as it is pushed up the 5.00-m ramp to a height ℎ=3.00 m.

How does the work done on the box compare to the change in gravitational potential energy Δ?grav that the box undergoes as it rises to its final height?
