1. The problem statement, all variables and given/known data What is the orbital speed of a satellite of mass 490 kg in geostationary orbit? 2. Relevant equations Fg= G m1m2/r 3. The attempt at a solution I don't really know where to begin... I know the period is 24 hours because it is geostationary, and the height is 35880, because that is the altitude that they orbit.... What am I suppost to do now?
