y (cm) 2 O 2 6 8 x (cm) Consider the system of three particles. The masses of the particles are m1 = 0.22 kg, m2 = 0.33 kg, and m3 = 0.30 kg. Their (x,y)-coordinates (in cm) are m1 = (3,2) cm, m2 = (7,0) cm, and m3 = (1,-1) cm as shown in the figure above. What is the y-coordinate of the center of mass? Give your answer in cm to two significant figures (unless you obtain an integer)
