v' +
v = g.
t + ro
If the water drops from stationary, solve for v(t).
![A water droplet evaporates before they reach the ground.
Figure 1: Water droplets (source]
In this situation, a few assumptions are made:
a) At initial point, a typical water droplet is in sphere shape with radius r and remain spherical
while evaporating.
b) The rate of evaporation (when it loses mass (m)) is proportional to the surface area, S.
c) There is no air-resistance and downward direction is the positive direction.
To describe this problem, given that p is the mass density of water, r,is the radius of water before it
drops, m is the water mass, V is the water volume and k is the constant of proportionality.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe6e6388d-406c-43bf-aac6-eddcc7d9134f%2F093545aa-4951-46a1-baca-e523fd993b6f%2Fmrjq85g_processed.png&w=3840&q=75)
