Upon exiting a cloud base, assume that drizzle falls for 100 seconds at its terminal velocity (1.5 m/s) before evaporating. In this case, would drizzle reach the surface if it is located 200 meters below the cloud base?

Sophie Chapman · Answer 1

distance = 150 m

Explanation:

time of fall, t = 100 s

terminal velocity, v = 1.5 m/s

The terminal velocity is a constant velocity by which a drop falls such that the net force acting on the drop is zero. The weight of the drop is balanced by the backward dragging force due to air resistance.

distance = velocity x time

distance = 1.5 x 100 = 150 m

So, in time 100 s the dazzle does not reach to the ground.
