A spherical raindrop of mass 0.0108 g and radius 1.37 mm falls from a cloud that is at a height of 1165 m above the ground. Assume the drag coefficient for the raindrop is 0.60 and the density of the air is 1.3 kg/m3. What is the raindrop's terminal speed?

What would be the raindrop's speed just before landing on the ground if there were no drag force (no air resistance)?
