Period of Orbit

  1. Apr 13, 2009 #1
    1. The problem statement, all variables and given/known data
    What is the period of revolution (in minutes) of a satellite orbiting Earth at 161000 m?

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

    3. 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).

    Lol, happens all the time, My friend saved the mass and radius of the earth in his calculator storage, and accidentally used mass for radius and radius for mass :D
    well good luck any way,glad You made it.

    Should pi be squared in this equation?
