## Homework Statement

A boat moving at constant speed v through still water experiences a total frictional drag F.

What is the power developed by the boat?

a) 1/2Fv b) Fv

## The Attempt at a Solution

I know the correct answer is b. My confusion is why is a incorrect?

My reasoning: The boat experiences a total drag of F. Which means at every point the boat experiences a resistance where R < F. Thus to steer at v, we have to apply a force of R. Which will provide the only option 1/2Fv.
