Calculate the moment of inertia of thkg fbs)1:86hl q rvtx9e array of point objects shown in Filw48v :5iz uq/xiy ktsg2+h3 bg. 8–43 albk hs8qwii/vuz 3t 2x+4g: y5bout (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?
