Consider the following mass distribution where the x- and y-coordinates are given in meters: 5.0 kg at (0.0, 0.0) m, 3.4 kg at (0.0, 3.6) m, and 4.0 kg at (3.4, 0.0) m. Where should a fourth object of 7.2 kg be placed so that the center of gravity of the four-object arrangement will be at (0.0, 0.0) m? X : m m
