Center of gravity

  1. Jan 17, 2013 #1
    1. The problem statement, all variables and given/known data
    If Bethany and Serendipity each exert a force of 350 N on each arm of a wheelbarrow with 1.25 m arms and carry Cardinal Glick in the bucket, who has a weight of 1,050 N, where is the center of gravity of the bucket and the Cardinal with respect to the wheel?

    Pointers would be nice, as I'm not sure how to go about this. All help is welcome.

    The wheelbarrow's arm is a lever.

    Yes, I realize this bit. The part I don't get is how to find the center of gravity, especially since the bucket was never assigned a length.

    The length is given - this is the arm's length. Google for "wheelbarrow" and look at pictures if that is not clear. The center of gravity of the bucket + load is where the downward force applies to the arm.
