Here is the problem which I am struggling on, please help me!
Problem: Assume that the moon orbits the earth in a circular orbit. From the observed orbital period of 27.3 days, calculate the distance of the moon from the center of the earth. Assume that the moon's motion is determined solely by the gravitational force exerted on it by the earth, and use the mass of the earth, which is 5.97 1024 kg. m.
Please show work I think I have the solution just not positive.
