a geosynchronous satellite orbits at a distance from earth's center of about 6.6 earth radii and takes 24 h to go around once. what distance in meters does the satellite travel in one day? what is its orbital velocity in m /s?

Answer 1

The earth's average radius is 6378 km, as I recall. (It is thicker at the equator)

Multiply that by 6.6 for the orbit radius, R.

2 pi R is the distance travelend in a day.

Divide that by the number of seconds in a day to answer the last question.
