1. The problem statement, all variables and given/known data Three odd-shaped blocks of chocolate have the following masses and center-of-mass coordinates: (1) 0.310 kg, ( 0.200 m, 0.310 m); (2) 0.410 kg, ( 0.110 m, -0.380 m); (3) 0.200 kg, ( -0.280 m, 0.610 m). Find the x coordinate of the center of mass of the system of three chocolate blocks. 3. The attempt at a solution This is how I commenced, I took (mass1*x1+mass2*x2+mass3*x3)/(m1+m2+m3) and got .051 this should be right but I got it wrong. I then redid the calculation and this time I got .05 not that much difference, I only got one try left, and don't think this is right because they are so close together. I did the y the same way and got it right. :S Please and thank you.
