Question

How much work is done by a man who uses a force of 7 Newtons to push a box 3 meters across the room?

Answer 1

Answer:

21 J

Step-by-step explanation:

Work = Force * Distance

We know the force to be 7 Newtons.

We know the distance to be 3 meters.

multiply 7* 3

21

Answer 2

Answer: 21 J (Joules) of work done.

Step-by-step explanation:

W = Fs, where F is force and s is displacement.

F = 7 N

s = 3 m

W = 7 N * 3 m = 21 N*m, or 21 J
