Solve the following questions given below:

Question I: 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 2 µm and a density of 0.4 g/cm³.

________m/s

Question II: 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 answer will explain why pollen stays in the air for a very long time. (Assume the density of air to be 1.3 kg/m³).

_______s

Please show me step by step or type in formulas used. I am so lost!!
