maximum speed - 10 points first correct answer!?

Suppose that the force due to water resistance of a microbe swimming through a fluid is F=bv, where v is the constant swimming speed and b is a constant. Assuming that the microbe is expending a power P in swimming, the maximum speed of the object is...

1. sqrt(P/b)

2. P/b

3. P/sqrt(b)
