Earth 's radius is about 6400 km ... if we put a satellite in orbit 6400 km above Earth's surface (constant distance, circular orbit), [ a) what is Earth gravity 's intensity at the satellite's location? ] [ b) what should the satellite's orbital speed be? ] c) what should the satellite's orbital (time) period be?
3583 s = 0.995 hours
7936 s = 2.204 hours
10134 s = 2.815 hours
1141 s = 0.317 hours
50 672 s = 14.08 hours
14 332 s = 3.98 hours
