If a satellite is orbitting the earth 710km above the earths surface, and it's velocity is 7,406.8 meters/sec, what is it's cetripedal acceleration??
centripetal acceleration = V^2/R
For R, add 710,000 m to the radius of the earth. Use meters
The earth's radius is about 6400 km, but you should look it up.
