Question

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?

Answer 1

`W=Fd` and `P=W/t`, so `P=(Fd)/t`

`P=(300xx30)/3=3000` `W` or `3` `kW`

Explanation:

Work = Force x Distance

Power = Work/Time

In this question, the mass is not used.
