Falling Raindrop

A raindrop, whose initial size may be considered negligible, falls from a height h and increases its size by accreting (gathering) all the mist it encounters. If the mist is of uniform density ρ and extends to the ground, report the equation of motion of the falling raindrop.

P.S.: Equation of motion refers to an equation in position, velocity and accelaration.

  2. i didnt provide u with the value of coeff. of viscosity.. so u may neglect viscosity.. that's all..

  3. btw.. viscosity wont be present at all in this case! ;)

  4. people may leave their answers at the DE they get.. obviously its difficult to solve such a bad DE!
