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)
