The bacterium Escherichia coli propels itself with long, thin structures called flagella. When its flagella exert a force of 1.50×10−13 N, the bacterium swims through the water at a speed of 30.0 μm/s. Assume that the drag force on the bacterium is directly proportional to the speed with proportionality constant , such that =. Determine the speed 2 of the bacterium in water when the force exerted by its flagella is 2.75×10−13 N. Answer in units of micrometers per second.

pls dont give me the answer i just need the equation
