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 Fdrag = -bu in water, where the drag coefficient b is approximately 0.290 kg/m. If the paramecium's speed v is 0.000142 m/s, what is the magnitude of the propulsion force that the creature must generate to move at this constant speed? magnitude: 0 N
