Drag force or drag coefficient? I have a vague recollection of the drag
force as having a fairly specific velocity dependence.

I'm also curious about the experimental and computational details,
especially those that allow one to compute the drag coefficient from data
taken in a typical classroom setting without making _ad hoc_ assumptions,
and without using a wind tunnel.

If this can be pulled off under the stated conditions, I have to agree that
it would be worth seeing.
