Calculate the moment of inertia of the array of poin *gw2fvmfm(mndnj1mzqev7(ab (*,z) o 1+c qstzq.h*n;p m 9kl objects shown in Fig. 8–43 abouplmh;n z9q k.*t (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?
