I've already searched Physics StackExchange for some similar question but I didn't find anything about this.
- Earth is a perfect sphere with it's core (X,Y,Z) -> (0,0,0) as a reference-frame center
- Air resistance can be ignored
- Earth rotation can be ignored
- Moon gravity-effect can be ignored
And if I know (projectile starting properties):
- Current Earth GPS-coordinates
- Starting angle
- Starting direction (relative to (0,0,0))
- Starting velocity (can be larger than Earth-escaping speed)
- (mass of the projectile is irrelevant (I guess) when we know starting velocity of the projectile)
How could I calculate aprox. coordinates of a projectile landing somewhere around the Earth globe (OR detect that projectile will "leave" the Earth)?
EDIT: I've found tons of links on the net about projectile trajectories when starting velocities are quite small (& Earth can be considered like a flat plane), but non about upper situation.
