1. The problem statement, all variables and given/known data A horizontal force of magnitude F = 197 N is used to push a box of mass m = 5 kg from rest a distance d = 13 m up a frictionless incline with a slope q = 34°. 2. Relevant equations How much work is done on the box by the gravitational force during this same displacement? 3. The attempt at a solution Wg=mgh Wg=5*9.81*7.3 i got 7.3 by using sin34=h/13 Wg=358.1 J The answer i got is wrong according to the online hw. What am i missing? did i use the wrong formula?
