Answer to Question #285341 in Physics for Olu101

Question

To keep a vehicle moving at a constant speed "V" require power "P" from the engine. The force provided by the engine is?

Answer 1

The power by definition

$$P=\rm\frac{work\: done}{time}$$

$$P=\frac{W}{t}=\frac{Fs}{t}=Fv$$

Hence, the force

$$F=\frac{P}{v}$$
