A spherical raindrop 1.9 mm in diameter falls through a vertical distance of 5000 m. Take the cross- sectional area of a raindrop = ², drag coefficient = 0.45, density of water to be 1000 kg/m³, and density of air to be 1.2 kg/m³. (a) Calculate the speed (in m/s) a spherical raindrop would achieve falling from 5000 m in the absence of air drag. m/s (b) What would its speed (in m/s) be at the end of 5000 m when there is air drag? m/s
