Homework Statement
Water vapor condense in a raindrop with rate μ units of mass per time.
The raindrop starts with 0 velocity with initial mass $$ M_0 $$ and falls horizontally. Find the space it traverses as a function of time (g is given).
Homework Equations
∂m/ ∂t= μ
The Attempt at a Solution
Assuming that the mass dm of vapor to be condesed has a total velocity v0, and using Newton's law, I have [itex]g= \frac{dv}{dt} + \frac{dm*(v-v0)}{dt*m}[/itex] . From there the only thing i could think is that I could write dv/dt as dv/dm*dm/dt but it doesn't seem to help...
