Hi guys,
I'm currently doing a little project an I need to calculate the speed of a satellite around the sun! I'm currently trying with the Earth, but i have some problem.
When I'm using this formula : (2*Pi*a*Sqrt(1-e2))/T(1±e)
I get an answer in km/s which seams pretty good. (29,75 km/s)
But when I'm using this one : Sqrt(G*M*(2/r)-(1/a)) I'm getting 1,32*1017
I don't really know how I can transform that answer into something in km/s
If I'm not clear enough, feel free to ask me questions!
Thanks!
