Question

How much work is done by a person who pushes a lawnmower with a force of 50N at a distance of 450m?

Answer 1

Work= force X distance
So;
W= 50Nx450m
W=22,500N•m
W=22,500 J

50N is the force being used to push the lawnmower, and it goes 450m, you just multiply them together to get the answer of 22,500.
