​A spherical raindrop question

timer Asked: Sep 25th, 2015

Question description

A spherical raindrop of mass 0.0112 g and radius 1.39 mm falls from a cloud that is at a height of 1157 m above the ground. Assume the drag coefficient for the raindrop is 0.60 and the density of the air is 1.3 kg/m3What 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)?

I don't understand how to figure these out
