A) Calculate the location of the center of mass of the earth-moon system (that is, find the distance of the center of mass from the earth's center). Use data from Appendix E in the textbook and assume the orbital radius of the moon is equal to the distance between the centers of the earth and the moon.
B) What can you say about the position of the center of mass with respect to the earth's surface?
