Center of mass

  1. Oct 29, 2009 #1
    1. The problem statement, all variables and given/known data
    ____
    l _ l
    l_l l_l

    Find the y-coordinate of the center of mass. Each side l / _ is length a.
    I got an answer of 1.25a, but that isn't right.

    2. Relevant equations



    3. The attempt at a solution

    Area of each section * x-coordinate of center of mass. (the area missing is negative)
    Then divided by the total area

    Welcome to PF!

    Hi phsyics_197! Welcome to PF! :wink:
    (hmm … I can see from the "QUOTE" box that that's supposed to be two squares on level 0, and three squares on level one)

    Show us how you got 1.25, and then we can see what went wrong, and we'll know how to help! :smile:
