68. The rotational inertia of the passengers is (to a good approximation) given by Eq. 10- 53: Im R N m R == ¦ 22 where N is the number of people and m is the (estimated) mass per person. We apply Eq. 10-52: 2 11 WI N m R ωω where R = 38 m and N = 36 × 60 = 2160 persons. The rotation rate is constant so that ω = θ / t which leads to
