I don't understand how this is incorrect! Any help is appreciated :)

A single-celled animal called a paramecium propels itself quite rapidly through water using its hair-like cilia. A certain paramecium experiences a drag force of $$F_{\mathrm{drag}}=?b{v}^2$$ in water, where the drag coefficient $$b$$ is approximately $$0.310\mathrm{kg}/\mathrm{m}$$. If the paramecium's speed $$v$$ is $$0.000147\mathrm{m}/\mathrm{s}$$, what is the magnitude of the propulsion force that the creature must generate to move at this constant speed? magnitude:
