Question
REMARKS The normal force n, the gravitational force m8, 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.
