Question

A group of people move a large box that weighs 90 Newtons, 10 meters in 20 seconds, how much power was used?

Answer 1

P = 45 W

Explanation:

Given that,

The weight of a box, W = 90 N

Distance moved, d = 10 m

Time, t = 20 s

We need to find the amount of power used. The rate of doing work is called power It can be calculated as the formula,

`P=(W)/(t)\\\\P=(Fd)/(t)\\\\P=(90* 10)/(20)\\\\P=45\ W`

So, 45 W of power was used.
