Explanation Calculation: Refer to the Appendix E “Astrophysical Data” in the textbook. The mass of the Earth is m E = 5.97 × 10 24 kg . The mass of the Moon is m M = 0.0735 × 10 24 kg . The distance between the moon and the earth is 3.85 × 10 5 km . Sketch the Moon-Earth combination as in Figure 1. Refer to Equation 9.2 in the textbook. Find the mass at the third vertex using the equation. x c m = ∑ m i r i → M = ∑ m i r i → ∑ m i = m E x E + m M x M m E + m M (1) Here, the distance of the Earth’s center from the center of mass of the Earth-Moon system is x c m , the mass of the Earth is m E , the distance of the Earth from the origin is x E , the mass of the Moon is m M , and the distance of the Moon from the origin is x M
