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...

I fixed my equations: they're ax = a*cos(T) and ay = a*sin(T) where ax is the x component and ay is the y component of acceleration, r is the earth-moon distance, and T is the angle with the x axis). The problem is I need to derive T as well and plug that into the two equations. if those...

By the way i just noticed that those were supposed to be ASIN and ACOS. sorry. And thanks for clearing that up about the m value. Anyways, what would i use then if I'm not supposed to apply sine and cosine? Should ASIN and ACOS work?

well x and y are the coordinate positions from the Earth (which is at the origin) so this will make a triangle with the x-axis. Using trigonometry, x would be the adjacent side and y would be the opposite side, and r would be the hypotenuse (distance from Earth to moon). I'm supposed to use...

Hello, I need help on deriving equations for the moon's acceleration around the earth. I've found that the total acceleration is a=Gm/r^2 (G is gravitational constant, m is mass of moon and r is the Earth to moon distance) what i need to do is split this into its x and y components, and derive...
