Answer: vp= 17 723 mi/hr

3/224 Just after launch from the earth, the space-shuttle
orbiter is in the 37 x 137-mi orbit shown. At the
apogee point A, its speed is 17,290 mi/hr. If nothing
were done to modify the orbit, what would its speed
be at the perigee P? Neglect aerodynamic drag.
(Note that the normal practice is to add speed at A,
which raises the perigee altitude to a value that is
well above the bulk of the atmosphere.)
