Consider the following distribution of objects: a 3.00-kg object with its center of gravity at (0, 0) m, a 2.20-kg object at (0, 3.00) m, and a 5.40-kg object at (4.00, 0) m. Where should a fourth object of mass 7.00 kg be placed so that the center of gravity of the four-object arrangement will be at (0, 0)?

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, 4.4) m, and 4.0 kg at (3.4, 0.0) m. Where should a fourth object of 7.0 kg be placed so that the center of gravity of the four-object arrangement will be at (0.0, 0.0) m?

Consider the following mass distribution, where $x-$ and $y-$coordinates are given in meters: 5.0 kg at (0.0, 0.0) m, 3.0 kg at (0.0, 4.0) m, and 4.0 kg at (3.0, 0.0) m. Where should a fourth object of 8.0 kg be placed so that the center of mass of the four-object arrangement will be at (0.0, 0.0) m?
