III Revision questions

The lunar module question is a variation on the orbital transfer question `how to get from a circular orbit at radius A to a circular orbit at radius B?' The following solution recaps the solution to that question. Note however that we don't want to get into circular orbit at B, we want to become stationary relative to the moon. So the final step of the solution (which is omitted) should go as follows: (a) compute the momentum at B when on the elliptical transfer orbit; (b) use an impulse of that size to bring yourself to a stop.
