1. The problem statement, all variables and given/known data Consider the following mass distribution where the xy coordinates are given in meters: 5 kg at (0.0, 0.0) m, 3 kg at (0.0, 4.0) m, and 4 kg at (3.0, 0.0) m. Where should a fourth object of 8 kg be placed so the center of gravity of the four-object arrangement will be at (0.0, 0.0) m? 2. Relevant equations Just guessing, Xc of m = [tex]\Sigma mi*xi\Sigma mi 3. The attempt at a solution I am guessing that it should be in the bottom left of the xy coordinate. Buy I don't know how to start the problem.
