A uniform square of mass 4 kg and sides 2 m and negligible thickness is centered at the origin. Determine the center of mass of this square using symmetry arguments. Suppose then that the 1 m × 1 m section in the fourth quadrant is removed. Where is the center of mass of this new object? Do this calculation by treating the mass of each remaining 1 m × 1 m section as residing at its center of mass and then fnding the centers of mass of these “masses”.
