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

Answer:

P = 45 W

Step-by-step 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,

$P=\dfrac{W}{t}\\\\P=\dfrac{Fd}{t}\\\\P=\dfrac{90\times 10}{20}\\\\P=45\ W$

So, 45 W of power was used.
