Calculate the moment of inertv3do:b tsfn b d bn;a410x53wcia of the array of point cd6aj,t hjv:0)d *v2py5tmcl 8gr m-p objects shown in Fig. 8–43 ab0m)hgamd t*- p vd yc:5c6r8jvp j2t,lout (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?
