above the Martian surface. At this point of closest approach, the engines will be
fired to slow down the spacecraft and place it in a circular orbit 300 km above the
surface. (a) By what percentage must the speed of the spacecraft be reduced to
achieve the desired orbit? (b) How would the answer to part (a) change if the
distance of closest approach and the desired circular orbit altitude were 600 km
instead of 300 km? (Note: The energy of the spacecraft–Mars system for a
parabolic orbit is E = 0.)
