Calculate the moment ofo,u a w6b-ba*5 ths(qi inertia of the array of point objects shown in(uymv yi3l*ru- x uanuf,n 159 Fig. 8–43 aboutuumfnx(,y vra1u5y -i l39n*u (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?
