The moon and earth rotate about their common center of mass, which is located about 4700 km from the center of earth. (this is 1690 km below the surface.)
a. calculate the magnitude of the acceleration due to the moon's gravity at that point.
b. calculate the magnitude of the centripetal acceleration of the center of earth as it rotates about that point once each lunar month (about 27.3 d) and compare it with the acceleration found in part (a). comment on whether or not they are equal and why they should or should not be.
