Homework Statement
A 450kg satellite is to be placed at an altitude of 2.45 x 10^6m above the Earth surface. Calculate the period the satellite will have when orbiting at that altitude.
Homework Equations
m2g = Gm1m2/R^2 = m2v^2 = m2(4pie)^2 R /T^2 = m2 2pie v/T
Ac=4pie ^2 R / T^2
The Attempt at a Solution
Alt= r- rp
2.45x10^6m= r -6.37x10^6m
8.82x10^6m = r
I don't no what equation to use next
