A communications satellite is directly overhead at 9 p.m. After being tracked for one day, the satellite was detected at the same spot overhead at 9 p.m. Its orbit radius was measured to be 42,200 km and the circumference was 265,000 km. What is the magnitude of the satellite’s total displacement relative to Earth’s center?

Back

0 km
