sorry, but unless the acceleration was hundreds of g's over such a short distance, it wouldn't factor much.

Launch from Earth needs 3 g's for about 15 minutes. The moon is 1/6 the surface g, and less integrated deltaV, but still needs a good "kick"

        A trebuchet would be a lot easier to aim than a inline mass driver. - Lee - 12/28/2005 9:19:50 PM
