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

The formula to calculate work done is -

Work done ( in joule, J) = Force (in Newton) X Distance (in meters)

So, we will use the formula to calculate work done,

Here, force is given as = 7 newtons

Distance is given as = 3 meters

So, work done will be -

Work done ( in joule, J) = 7 Newtons X 3 Meters

Work done ( in joule, J) = 21 J (in joule)

Answer 2

If I remember right that if he uses 7 newtons to push a box 3 meters you multiply the force times length and I think you get 21 I think that's correct
