1. The problem statement, all variables and given/known data A geosynchronous satellite is used for communication and stays at the same place above the equator all the time. Calculate the a)Height of the satellite b)Speed at which it travels. 2. Relevant equations v=2πr\t a=v2/r F=Gm1m2\r2 3. The attempt at a solution I'm not sure how to start this,but i started with velocity but didn't know what radius to use. Is it double the radius of the earth?
