Question

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

Answer 1

6.67 watts

Step-by-step explanation:

power=force × velocity

10×20÷30

=6.67 watts

Answer 2

6.67 Nm/s

Step-by-step explanation:

As we know, the rate at which work is done is called power.

Power = Work done/ Time

Power = F * D / T

Where,

F = Force

D = Distance

T = Time

Given,

F = 10N

D = 20m

T = 30s

Power = 10*20/30

Power = 200/30

Power = 6.67 Nm/s

Hope it helps! :)
