Homework Statement
Homework Equations
g=GMm/r^2
e=c/a
g=v^2/r
The Attempt at a Solution
a) v^2/r=GM/r^2 m<<M
v^2=GM/r
v=SGRT(GM/r)
I don't think this is valid though since the orbit is not circular. I don't know how to alter the equation so it also applies to the elliptical orbit of the problem.
Thanks so much for any help.
