Inertia of Momentum

  1. Apr 15, 2013 #1
    1. The problem statement, all variables and given/known data

    Given: A flat dance floor of dimensions lx = 17mbyly =15mandhasamassofM = 1100 kg. Use the bottom left corner of the dance floor as the origin. Three dance couples, each of mass m = 100 kg start in the top left, top right, and bottom left corners.
    What is the initial y coordinate of the cen- ter of gravity of the dance floor and three couples?
    Answer in units of m

    2. Relevant equations

    xcm: m1x1 + m2x2/m1+m2

    3. The attempt at a solution
    I am so lost any help would be appreciated! Thanks

    Hello Krobinson2851

    Why don't you just apply the equation you have written down (and the equivalent one for yCM).
    If you get stuck, show us what you've done.
