Explore the movement of raindrops in windless weather. We can think of raindrops as spheres. Assume that raindrops are subjected to air resistance and raindrops in the process of falling vertically.
(1) Finally, the raindrops are balanced: mg=kSvn2,
Where m=ρV,
V=43πr3，
S=πr2，
The solution is VN = 4ρGR3K；; .
(2) according to Newton's second law, mg-ks (vn2) 2 = ma,
Because mg=kSvn2,
The solution is a = 34g.
Answer: (1) The final velocity vn of raindrops is VN = 4ρGR3K；;
(2) The speed reaches V? The acceleration a of raindrops at n2 is 34g. ..
