# A vehicle requires a force of 300 N to move 30 m at constant velocity in 3 s. What power does the vehicle's engine exert?

Jan 18, 2018

$W = F d$ and $P = \frac{W}{t}$, so $P = \frac{F d}{t}$

$P = \frac{300 \times 30}{3} = 3000$ $W$ or $3$ $k W$

#### Explanation:

Work = Force x Distance

Power = Work/Time

In this question, the mass is not used.
