Sarah uses an inclined plant to load a chest into her truck. If she does 84 Joules of work, and the inclined plane is 3 meters long, how much force does she expend?
1 answer
The force Sarah expends is 28 Newtons. This can be calculated by dividing the work (84 Joules) by the length of the inclined plane (3 meters): 84 Joules / 3 meters = 28 Newtons.
