Picture 2 of 3 from Album Miscellaneous
 My ballistics formula. Needs some cleaning up, obviously, but hey. It works. Variables ----------------------------- x0, y0 = Initial (x, y) points of the projectile. θ = Angle at which the projectile is fired. d = Diameter of projectile m = Mass of projectile v0 = Muzzle Velocity of projectile Cd = Drag coefficient (best keep at 0.295 for bullets and other large bullet-like objects) p = Atmospheric Pressure (I usually keep it at 1013.25 hPa if I have no distinctive weather system) t = Temperature (Again, usually keeping it at 80F) g = Gravitational force (you never know if you're shooting off of, say, Pluto.) R = Specific gas constant (8.314 472(15)) Have fun! (PS, Z can be replaced by Y if you are using this for a 2D system) Picture Added 08-31-2009 12:38 AM Added by Programmer
