3.5^2 Pi = area (convert to meters)
so we get ..
Fdrag = v^2 * 0.00680265...
that wasn't so bad eh?
now just do some discrete modeling assuming a is constant over small intervals (deltat is .1 in this example.. smaller would be more accurate, but this is a rough estimate anyway, density isnt contant and spin effects would negate this..)
*edit* - I /shoud/ be cramming for my finals, but if I finish my final code, I'll paste the ballistics table here with variables v, vbot, theta... It shouldn't be that bad, once I'm done with that... I can take into account lateral air resistance (the list keeps going). I'll post them here when I'm done (hopefully after friday, my physics final =p )
*edit 2* - is someone with matca willing to lend some processing time? I realized that a delta t < .1 (ie .001) takes a ridiculously long time... if anyone is willing to help generate ballistics table, I'd be grateful..

Sorry Tatsu but that math is WAY to advanced for me.
However if you need some lended processing power I will do what ever you ask, but you are going to have to give some pretty clear instructions.
