2. A raindrop with radius R = 1.5 mm falls from a cloud that is at height h = 1200 m above the ground. The drag coefficient C for the drop is 0.60. Assume that the drop is spherical throughout the fall. The density of water is 1000 kg/m³, and the density of air is 1.2 kg/m³. What is the terminal speed of the drop? _______m/s.
