Consider the following mass distribution where the x- and y-coordinates are given in meters: 5.0 kg at (0.0, 0.0) m, 2.8 kg at (0.0, 4.8) m, and 4.0 kg at (2.9, 0.0) m. Where should a fourth object of 9.3 kg be placed so that the center of gravity of the four-object arrangement will be at (0.0, 0.0) m?

x = m

y = m
