Thanks for the reply.
With the simple model you mention, does the drag proportional to v3 replace the drag proportional to v2?
With regards to the function for density, I think the calculus is getting too complicated.

I am looking at the problem of a freefalling sphere and want to calculate time taken to fall a distance. I want to model drag as well as take account of the varying density in the atmosphere.
I am using Drag = 1/2*A*Cd*v2*ρ; A - cross-sectional area, Cd - drag coefficient, v2 - velocity...
