Question

A man exerts 500 Newtons of force to move a piece of furniture 2 meters. If it takes him 4 seconds to move the furniture, how much power does it require?

Answer 1

Step-by-step explanation:

Work = (force) x (distance)

The work he did: Work = (500 N) x (2m) = 1000 joules

The rate at which he did it (power):

Work/time = 1,000J/4s

= 250 joules/sec

= 250 watts

Therefore he used 250 watts of power to move the furniture
