Question: Calculate the terminal speed for a pollen grain falling through the air using the drag force Equation 3.20. Assume the pollen grain has a diameter

Calculate the terminal speed for a pollen grain falling through the air using the drag force Equation 3.20. Assume the pollen grain has a diameter of 1 mm and a density of 0.2 g/cm³. If this grain is released from the top of a tree (height 10 m), estimate the time it will take to fall to the ground.
