Homework Statement
Communications satellites are placed in a circular orbit where they stay directly over a fixed point on the equator as the Earth rotates. These are called geosynchronous orbits. The altitude of a geosynchronous orbit is 3.58e7 m.
Homework Equations
v=2∏r/T
a=(v^2)/r
The Attempt at a Solution
In the previous problem, I was asked to calculate the period of the satellite, which is obviously 24 hours.
I figure that g is another form of radial acceleration (both point to the center of earth).
Therefore, I calculated v using the period equation. Once I got v I used the radial acceleration equation to arrive at my answer for g.
It's wrong though- can anyone explain why and set me on the right track?
