Homework Statement
Determine how long it would take for the satellite to make 1 complete revolution around earth
A 500 kg satellite is orbiting earth, radius of Earth is 6.38 x 10^3 km, and acceleration of gravity as the orbital altitude of 160km is the same as Earth basically 9.8.
Homework Equations
fc=mv^2/v
fc= 4pi^2*m*r/ t^2
The Attempt at a Solution
I've tried using both above equations. usually i started with energy equations like eg= mgh and ek= 1/2mv^2 to find velocity. Then I would put it into the fc= mv^2/v and find force then i would put that info into fc= 4pi^2*m*r/ t^2 to find the time. But none of it came out with the right answer which is 5132.8 seconds, I have tried everything I could think of. If you could help me please do.
