Four masses of different colors and masses are arranged in the XY coordinate system where x- and ty-coordinates are given in meters: A red ball of mass 5.00 kg is at (0.0, 0.0) m, a green ball of mass 3.0 kg is at (0.0, 4.0) m, and a pink ball of mass 4.0 kg is at (3.0, 0.0) m. Where should a fourth white ball of mass 8.0 kg be placed so that the center of mass of the four-object arrangement will be at (0.0, 0.0) m?
