Calculate the moment ofmv2wl8m8w)fw inertia of the array of point objects shown in Fig. l,0e xn7+kjjrc u.(vmd+c;ns8–43 kn0 rje ;uld+(x7ms ,c.ncv+j about (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?
