Hey, I'm doing a math project on projectiles (I think) and I was wondering how to determine how lets say... an artillery shell would act after it leaves the barrel. I was wondering when the forces of gravity would overcome the initial propulsion force and begin to bring the shell down. I know that the angle of the shot, wind etc. would effect this, but just like a rough estimate. I'm guessing the flight path would look something like a stretched out parabola, but I'm unsure about how to determine those factors.
