Trajectories

Now that the basics of the terminology and the dynamic equations have been presented, we shall begin to look at their uses in the form of prediction of trajectories. The aero-ballistician is usually faced with one of two problems: “If I want to hit a target at position x, to what elevation (and perhaps with how much propelling charge) do I have to elevate the weapon?” or “My weapon is elevated to elevation x and I expect muzzle velocity y-where is the projectile going to end up?”
