Space debris left from old satellites and their launchers is becoming a
hazard to other satellites. Calculate the speed of a satellite in an orbit
900 km above Earth's surface.
(Mass of Earth = 5,979 X 10^24 kg)
Consider 900 km as the distance between the satellite and Earth.
2.11 X 10^4 m/s
3.00 X 10^4 m/s
6.00 X 10^4 m/s
5.55 X 10^8 m/s
