Unformatted text preview: F N = 2 Mg ) that the center of mass speed (squared) is v 2 = gr , where r is the arc radius (0.48 m) Thus, the ball’s angular speed (squared) is ω 2 = v 2 /R 2 = gr/R 2 , where R is the ball’s radius. Plugging this into Eq. 105 and solving for the rotational inertia (about the center of mass), we find I com = 2 MhR 2 /r – MR 2 = MR 2 [2(0.36/0.48) – 1] . Thus, using the β notation suggested in the problem, we find β = 2(0.36/0.48) – 1 = 0.50....
