A thin rectangular plate of uniform area density ?1 = 1.14 kg/m2 has a length a = 0.540 m and a width b = 0.230 m. The lower left corner is placed at the origin, (x, y) = (0, 0). A circular hole of radius r = 0.043 m with center at (x, y) = (0.061 m, 0.061 m) is cut in the plate. The hole is plugged with a disk of the same radius that is composed of another material of uniform area density ?2 = 5.37 kg/m2. What is the distance from the origin of the resulting plate's center of mass? m
