Calculate the moment c p +/bwz 9kre2sa.4muof inertia of the array of point objects shown ix)u j zv)d hf94,hq:ourw6:spn Fig. 8–43 u9q) 4 x:6hfdvs uj)h:z,row pabout (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?
