Solve the all parts of following problem given below:
Problem: A spherical raindrop of mass 0.0162 g and radius 1.57 mm falls from a cloud that is at a height of 1173 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 raindrops speed just before landing on the ground if there were no drag force (no air resistance)?
Please explain each step to determine the raindrop's terminal speed.
