Re: Physic help

The lit programs I used were the ones that calculated the specific impulse
when given a exaust velocity, and the ones for calculating the terminal
speed/fuel mass ration/specific impulse.  Give 2 of the three and it figures
out the third.  There were actually 2 of the latter programs (both for staged
and single stage craft) and the numbers were close.

I don't see how energy content of the fuel would effect the calculations,
since that wasn't an imput.  Only the exaust velocity or specific impulse.
