The drag force for fast moving objects falling through a fluid is given by 1 2 DrhoAv2, where D is the drag coefficient, A is the cross-sectional area perpendicular to the direction of motion, rho is the density of the fluid, and v is the speed of the object. During a thunderstorm, a hailstone with a cross-sectional area of 8.15 ✕ 10−5 m2 and a mass of 4.50 ✕ 10−4 kg falls through the air. If the drag coefficient is 0.500, find the magnitude of the terminal velocity of the raindrop. The density of air is 1.20 kg/m3.
