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 ?drag=−??2 in water, where the drag coefficient ? is approximately 0.330 kg/m . If the paramecium's speed ? is 0.000137 m/s , what is the magnitude of the propulsion force that the creature must generate to move at this constant speed?
