1. The problem statement, all variables and given/known data Some communication satellites are put into a circular geosynchronius orbit in which the satellite remains above a certain postion on the Earth's equator as it orbits. Such a satellite would always be in the same position in the sky as seen from the transmitting or recieveing equipment of a communications broadcasting network. Find the angular speed of the satellites orbit necessary for it to reamin above the same point above the equator. What must be the orbitial radius of such a satellite? 2. Relevant equations (GMm)\r^2=mw^2r F=(GMm)\r^2 3. The attempt at a solution I solved for w=squareroot(GM\r) How am i to know what the radius is? I think i need another equation to input for the radius to find w. Then I can find the radius. Is this the right way to go?
