    Center of gravity????

    A uniform board 20.0cm x 10.0 cm has a mass of 200g. Masses of 50.0 and 80.0 grams are attached at two corners at the ends of one of the longer sides. Locate the center of gravity.

    you can firstly do it for one direction on xy plane. Firstly work on 50 and 80 for a line from x. then work on 200 and 130 for a line from y. the junction point of these two lines gives you the new center of gravity.
