Many species of bacteria can swim through fluidslike waterat speeds of around 10-5m/sconsider a spherical bacterium of radius 10-6m (1 micron). if the bacterium is swimming through water (with viscosity = 10-3n s/m2) and stops exerting force on the fluid, how long does it take for the bacterium to slow down to 1/100thof the original swimming speed? ignore gravitational effects as many bacteria are approximately neutrally buoy
