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?
WF =
2) How much work is done on the box by the gravitational force during this same displacement?
Wg =
3) How much work is done by the normal force of the slope on the box during this displacement?
WN =
4) How fast is the box moving after this displacement?
v =
