The moon is 3.85Ã-10^8 m from Earth, and it takes 27.3 days to orbit Earth...
A) At what speed is the moon traveling, relative to Earth? (Use units of m/s.)
B) Suppose a space colony is established on the moon. At some point, a clock on Earth and a clock on the moon are synchronized. A year later, how much time will the clockon the moon lag the clock onEarth?
