Question

If the average velocity of a car was found to be 22 m/s and the car exerted 110 Newtons of Force on the car’s wheels, how much power did the engine exert?

Answer 1

By the definition of the power, we have:

$$P=Fv=110\ N\cdot 22\ \dfrac{m}{s}=2420\ W=2.42\ kW.$$

Answer:

$P=2420\ W=2.42\ kW.$
