Find the terminal speed in µm/s of a bacteria (size 2 µm) falling in water. The drag force for a small object like a bacteria is given by Fdrag = Crv where C = 0.02 is the drag coefficient, r is the radius and v is the speed. Take the density of the bacterium to be 1100 kg/m3. (Assume the bacteria is spherical.)

Calculate the terminal velocity for a pollen grain falling through the air using the drag force equation. Assume the pollen grain has a diameter of 7 µm and a density of 0.3 g/cm3. If this grain is released from the top of a tree (height 11 m), estimate the time it will take to fall to the ground. Hint: The pollen grain will reach its terminal velocity very quickly and will have this velocity for essentially the entire motion. Your...
