Ok, so I have calculated an ideal speed of a projectile, but now I would like to know how it is affected by air resistance, although I'm only interested in the air resistance when it's outside the barrel, hopefully that'll simplify it a bit.
So the formula is: FD = [itex]\frac{1}{2}[/itex]CDρAv2
Can I find the affect on the projectile with a = F/m?
The projectile is an 8mm rod that is 290mm long, so how can I find the coefficient of drag? Also, I'm assuming 20°C at 0m above sea level, so the density of air is about 1.2kg/m3. Is that in the correct units for the formula?
Thanks for any help.
