Question

A person rearranging their living furniture expends 350 J of energy to push a coach 4.5 m across their living room. Calculate the amount of force they exerted.

Answer 1

The amount of force exerted is 77.7N

Explanation:

Given:

Work done, W = 350J

Distance, x = 4.5m

Force, F = ?

We know,

Work = force X distance

350 = F X 4.5m

F = 77.7N

Therefore, the amount of force exerted is 77.7N
