Answer to Question #141418 in Physics for an

Question

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

Answer 1

Power is the rate showing how quickly work can be done:

$$P=\frac{W}{t}.$$

Work is force times distance:

$$W=Fd.$$

Plug this into first equation:

$$P=\frac{Fd}{t}=\frac{10\cdot20}{30}=6.7\text{ W}.$$
