( 862, #15) Find the center of mass of a lamina in the shape of an isosceles right triangle with equal sides of length a if the density at any point is proportional to the square of the distance from the vertex opposite the hypotenuse.

Solution:

For the sake of notational simplicity, we take the constant of proportionality to be 1.

Then

The lamina's center of mass is ( 2a/5, 2a/5).
