A spherical raindrop 2.9 mm in diameter falls through a vertical distance of 4050 m. Take the cross-sectional area of a raindrop = tr“, 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 4050 m in the absence of air drag. m/s (b) What would its speed (in m/s) be at the end of 4050 m when there is air drag? m/s
