Question

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?
252 N
O 87 N
O 81 N
O 28 N

Answer 1

To find the force expended by Sarah, divide the work done by the distance traveled on the inclined plane. Sarah expends a force of 28 N to load the chest into her truck.

Step-by-step explanation:

To find the force expended by Sarah, we can use the formula:

Force = Work / Distance

Given that Sarah does 84 Joules of work and the inclined plane is 3 meters long, we can calculate:

Force = 84 J / 3 m = 28 N

Therefore, Sarah expends a force of 28 N to load the chest into her truck.
