The Earth and moon are separated by a center-to-center distance of 3.85x10^8m. The mass of the Earth is 5.98x10^24kg and that of the moon is 7.35x10^22kg. How far does the center of mass lie from the center of the earth?
I know you have to use the equation
Xcm=m1x1+m2x2/m1+m2
I don't know what x1 or x2 and i am not exactly sure what you measure x1 and x2 from and that is probably why i can't figure out how to use the equation.
