Homework Help: Center of Mass coordinates Question

  1. Jan 23, 2012 #1
    1. The problem statement, all variables and given/known data

    Four masses are connected by 17.4 cm long, massless, rigid rods. If massA=105.0 g, massB=231.0 g, massC=204.0 g, and massD=248.0 g, what are the coordinates of the center of mass if the origin is located at mass A?
    See attached picture.

    2. Relevant equations

    Xc.m = [itex]\sum[/itex]Δm x

    3. The attempt at a solution

    Xc.m = (0*105)+(248*17.4)+(204*17.4)+(231*17.4)/788

    How do you find the x and y coordinates?
