Calculate the moment of inertia ow *pa)g o w97o7gc/q0yj ko5zzf the array of point jjjn ()i5;vg robjects shown in Fig. 8–43 ab5gni( r;j)vjjout (a) the vertical axis, $kg \cdot m^2$ (b) the horizontal axis. Assume m=1.8 kg,M=3.1kg and the objects are wired together by very light, rigid pieces of wire. The array is rectangular and is split through the middle by the horizontal axis. $kg \cdot m^2$ (c) About which axis would it be harder to accelerate this array?
