Chapter 5, Problem 40P

& EST Estimate (a) the average distance between Earth and the Moon and (b) the diameter of the Moon, using the following data: the period of the Moon**#x2019;s revolution around Earth $(T_{\text{M}}\approx 28\text{ days)}$, the average radius of Earth $(R_{\text{E}}=6400\text{ km)}$, free-fall acceleration of objects near Earth’s - surface $(g=9.8{\text{ m/s}}^2\text{)}$, and the data in Figure Q5.15. The numbers on the photos are the times when the photos were taken (hh:mm:ss). Indicate any assumptions that you made. (Hint: Use Kepler’s third law.)
