Question

Four particles are arranged on an xy-coordinate grid. The masses and coordinates of each of the particles are given below:

m1: 0.3 kg x1: -3.5 m y1: 1.8 m

m2: 0.5 kg x2: 0.5 m y2: 2.7 m

m3: 0.34 kg x3: 3.9 m y3: 4 m

m4: 0.46 kg x4: -1.2 m y4: 3.9 m

Find the distance of the center of mass (in m) from the origin of the coordinate system.
