P11.2 Find the precession rate for the perigee for a nearly circular low-earth orbit. (The "perigee" for an orbit around the earth is the same as the "perihelion" for an orbit around the sun.) The radius of a low earth orbit will be about 6500 km and its period is about 90 minutes. Express your answer in arc-seconds per century. (Answer should be 1560 as/century)
