Take a look at the Lecture Files in Webcourses. There is a file for exercise 10, p. 73, which we were working on at the end of lecture. I made an error in the orbital speed computation, which was spotted by Morris and Katherine. The new lecture file for exercise 10 has the correct computation, along with some comments on the law of universal gravitation in chapter 5.Gracias, Katherine and Morris!! I was nappin'!!
