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.

we have to apply knowledge of mechanics or fluids?
ReplyDeletei didnt provide u with the value of coeff. of viscosity.. so u may neglect viscosity.. that's all..
ReplyDeletebtw.. viscosity wont be present at all in this case! ;)
ReplyDeletepeople may leave their answers at the DE they get.. obviously its difficult to solve such a bad DE!
ReplyDeletethe three eqn of motion
