A spherical raindrop (r = 0.0015 m) falls from a cloud. The drag coefficient is 0.60. The density of the water is 1000 kg/m^3 and the density of the air it falls through is 1.2 kg/m^3. The shape of the drop doesn’t change during the fall, and the terminal velocity is 7.3 m/s. At this terminal speed, what is the magnitude of the resistive force acting on the drop?
Homework Answers
magnitude of resistive force
F = 0.5 * rho * A * C v^2
F = 0.5* 1.2* (0.0015)^2* 0.6*7.3^2
F =1.355* 10^-4 N

2.) As a raindrop falls through a cloud, it collides with smaller droplets of mist and grows in mass (a) Derive a differential equation that relates the mass and velocity of the drop as it falls and accretes mass. Hint: Do NOT just differentiate d(mv)/dt, but start with the impulse-momentum theorem in differential form, like we did in the derivation of the rocket equation. Your "system" should include the raindrop itself and a small mass Δm of droplets with which...
