Question

A boy pushes a wheelbarrow up a hill . The boy does 506 J of work. If the child walks 10 m up the hill, how large of a force must the boy exert?

Answer 1

50.6 N

Step-by-step explanation:

The work done is equal to the force exerted times distance, therefore we can calculate the force using the following equation

W = Fd

F = W/d

Replacing W = 506J and d = 10 m, we get

F = 506 J/ 10 m

F = 50.6 N

Therefore, the answer is 50.6 N
