Moon's orbital acceleration

  1. Oct 16, 2005 #1
    Hello, I need help on deriving a equations for the moon's acceleration around the earth. I've already found the total acceleration (a=Gm/r^2) but what i need to do is split this acceleration up into its x and y components, and derive equations in terms of a, r, x, and/or y for any given position in the moon's orbital path

    So far I have ax = a*cos(T) and ay = a*sin(T) where T is the angle from the x-axis. What I'm having trouble with is deriving T. If those are wrong to begin with, can someone put me on the right track? Thanks!
