Question

The moon orbits 3.84 x 10^8m form the center of the earth. How fast does the moon travel in meters per second?

Answer 1

The circumference of the Moons orbit becomes C = 2PiR where Pi = 3.1416, R = 239,000, and C = ~1,501,681 miles. The time to travel this distance is 27.32 days or 655.68 hours. So the mean velocity is 1,501,681/655.68 = ~2290 miles/hour or 1024 m/s.
