The Interactive Physics, as I recall, gives one a

crude way of controlling air resistance. Thus one

can collect data by simulating experiments. Then

one can try to describe the data with a formula,

or test a preexisting formula. For real data one

should consult artillery manuals, I suppose.

What Alex wants, probably, is a formula which

gives the value of the air resistance coefficient

as a function of an asymmetry parameter, such

"the optimal launch angle," or "the difference

between the ideal and real ranges." I have

not seen such formulas.

As a straw man, I will offer as a measure, the optimal launch angle

for maximum range.

In projectile motion without resistance the path is a parabola.

With resisatance, the path is asymetric. Is there a standard way to

measure that asymetry? Can that measure be analytically related to

the

the resistance?
