Hi all
This question came up to me when I was playing a game called KSP (a space sim game):
Given an initial velocity and starting altitude, how do you create a 2D Cartesian equation of the orbit of that projectile around earth?
For example if I told you a projectile is traveling at a speed of 8000 m/s, an altitude of 350km and tangential to the surface of the earth, how do you create an 2D Cartesian equation of the orbit?
Also, assume (0,0) is the center of the earth.
So, the equation of the Earth would simply be
[itex]y = \sqrt{6378.1^2 - x^2}[/itex]
(The radius of the Earth is 6378.1 km)
Any input would be appreciated. Thanks!
