a) The x-coordinate of the center of gravity is .
b) The y-coordinate of the center of gravity is .
<h3>Determination of the coordinates of the center of gravity</h3>
Let suppose that each square has an <em>uniform</em> density, the coordinates of the center of gravity of each square with respect to the origin are, respectively:
The center of gravity of the <em>entire</em> system is found by applying definition of <em>weighted</em> averages:
Where ,
,
and
are weights of the each square, in newtons.
Now we proceed the coordinates of the center of gravity of the entire system:
a) The x-coordinate of the center of gravity is .
b) The y-coordinate of the center of gravity is .
