Question
On July 19, 1969, Apollo II's orbit around the moon was adjusted to an average orbit of 111km. The radius of the moon is 1785 km and the mass of the moon is 7.3e22 kg. a) How many minutes did it take to orbit once? b) At what velocity did it orbit the moon?

GM/R^2 = V^2/R
M is the mass of the moon.
R = 111 + 1785 km = 1896*10^3 m
G is universal constant of gravity
b) Solve for V.
a) period * V = 2 pi R
