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 point) Responses
28 N
81 N
252 N
87 N
To find the force expended by Sarah, we can use the formula for work:
Work = Force × Distance
Given:
Work = 84 Joules
Distance = 3 meters
We can rearrange the formula to solve for force:
Force = Work / Distance
Force = 84 Joules / 3 meters
Force = 28 N
Therefore, Sarah expends 28 Newtons of force to load the chest into her truck.
