A raindrop of radius R = 1.5 mm falling from a cloud at a height of h = 1200 meters above the ground. The drag coefficient C of the drop is 0.60. Assume that the descent is spherical throughout its fall. The density of water is Pw 1000 kg / m3, and the air density is Pa 1.2 kg / m3. If you know that a raindrop reaches its final velocity after falling a few meters. What is the final velocity?
