The normal force n with arrow, the gravitational force mg with arrow, and the upward component of the applied force do no work on the sled because they're perpendicular to the displacement. The mass of the sled didn't come into play here, but it is important when the effects of friction must be calculated and in the work-energy theorem. QUESTION How does the answer for the work done by the applied force change if the load is doubled
