Homework Statement


What is the period of revolution (in minutes) of a satellite orbiting Earth at 161000 m?

Homework Equations


T^2 = (4*pi*r^3)/(GM)


The Attempt at a Solution


Well, I plugged in the values, and got T = 5250.925844, but that's not right. T, would come out as seconds, right?

dividing your answer by 60 won't get the right solution? cause your T is in seconds..
in r you wrote (Re+161000) right?

K, I'm good with this now. Garbage in, garbage out; I was using bad numbers (over and over again).

T^2 = (4*pi*r^3)/(GM)
Should pi be squared in this equation?
