Question

When the engine of a car generated the power of 1800W, the car moved a distance of 20 metres in 30 seconds. What is the force produced by the engine of the car?

Answer 1

Given:

$P=1800\:\rm W$

$d=20\:\rm m$

$t=30\:\rm s$

The power produced by the engine of the car

$$P=Fv=Fd/t$$

Hence, the force produced by the engine of the car

$$F=Pt/d=1800*30/20=2700\:\rm N$$
