Chapter 8, Problem 87GP

Show that on a roller coaster with a circular vertical loop (Fig. 8–43), the difference in your apparent weight at the top of the loop and the bottom of the loop is 6 g’s—that is, six times your weight. Ignore friction. Show also that as long as your speed is above the minimum needed, this answer doesn’t depend on the size of the loop or how fast you go through it.
