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.
