A spacecraft (with its cargo, a satellite) is circling the Earth at a constant speed and an altitude of 600km. The combined mass of the craft and the satellite is 1.20×10^5 kg (kilograms). At phi = 0, the captain ejects the 1.10×10^4 kg satellite out the back. The speed of the satellite relative to the spacecraft at the time of separation is 100 m/s (meters per second). When the spacecraft reaches phi = pi, what will its altitude above the Earth be?
