Trying to study for physics and I'm already stuck. Help me out, /seacats/.
"Calculate the period of a satellite orbiting the moon, 120 km above the moon's surface. Moon's radius is 1740km."
The answer is 7.20*10^3s. I know the equations are GmM/r^2 = mv^2/r, and v = 2pir/T, and to solve for T. I'm guessing I am screwing up with the algebra somehow?
I keep getting T = sqrt(4pi^2*R^3/GM) = sqrt[4 * pi^2 * 1860^3 / (6.67 * 10^-11 * 7.35 * 10^22)] = 0.2276. What am I doing wrong?
