2) Secondly, find the acceleration on the bike.

3) Now you know the force (since you know the mass and acceleration), you can find the work involved in moving the bike any incremental distance.

4) To find the power, substitute velocity for distance in the work equation.

I believe this will provide you with the correct answer.

Assuming these variable are constant enough for an integral to be a multiple,

Work is force times distance.

Velocity is distance divided by time.

Power is work divided by time. Therefore Power is

This type of thinking ONLY works because force and velocity are constant. Since they are, though, it works :tongue2:
