A horizontal force of magnitude F = 116 N is used to push a box of mass m = 9 kg from rest a distance d = 13 m?
1)How much work is done by the force on the box?
2) How much work is done on the box by the gravitational force during this same displacement?
3) How much work is done by the normal force of the slope on the box during this displacement?
4) How fast is the box moving after this displacement?
