Re: [Phys-l] Rocket Science

Fowles equation 6.47 gives an orbit equation convenient for calculating a new orbit after a forward thrust from a circular orbit:

R(Theta) = Ro[(Vo/Vc)^2] / [1 + { (Vo/Vc)^2 - 1}Cos(Theta)],

where Vo is the speed at Theta = 0, and the orbit is a circle with radius Ro if Vo = Vc.

I think we need more info than JD supplied. We do not know Vo or Vc ; we only know Delta V = Vo-Vc.
