Solve the all parts of following question given below:
Question: A spherical raindrop of mass 0.0181 g and radius 1.63 mm falls from a cloud that is at a height of 1101 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.
Part A: What is the raindrop's terminal speed?
Part B: What would be the raindrop's speed just before landing on the ground if there were no drag force (no air resistance)?
I need help to determine the raindrop's terminal speed.
