Question

If a man moves a large box that weighs 10 Newtons 20 meters in 30 seconds, how much power was used?

Answer 1

Explanation:

Power = unit of work/unit of time

First, we need to determine the amount of work performed by the man.

Work = force x distance

The force exerted is 10 N

The distance is 120 m

Therefore, the amount of work = 10 * 120 = 1200 newton-meters

You should now be able to find the amount of power used by the man, Sarah
