Calculate the moment of inertia of wzmqbln*qvjfs3; 7ryd4* u19 the array of porxk1/dtmb-+l hbfu e1 yo0 *o2int objects shown in Fig. 8–43 about-y1ehr mbxk+uo d*f0/2bt 1l o (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?
