89. We note that its mass is M = 36/9.8 = 3.67 kg and its rotational inertia is IM R com = 2 5 2 (Table 10-2(f)). (a) Using Eq. 11-2, Eq. 11-5 becomes 2 22 2 2 2 com com com com com 111 2 17 222 5 2 1 0 v K I Mv MR Mv Mv R ω §· =+ = + = ¨¸ ©¹ which yields K = 61.7 J for v com = 4.9 m/s. (b) This kinetic energy turns into potential energy Mgh at some height h = d sin θ where the sphere comes to rest. Therefore, we find the distance traveled up the
