Four particles are positioned at the corners of a square that is 4.0 m on each side. One corner of the square is at the origin, one on the positive x axis, one in the first quadrant and one on the positive y axis. Starting at the origin, going clockwise, the particles have masses 2.3 kg, 1.4 kg, 3.7 kg, and 2.9 kg. What is the location of the center of mass of the system of particles?
