A uniform, square metal plate with side L = 3.50 cm and mass 0.087 kg is located with its lower left corner at (x, y) = (0, 0) as shown in the figure. Two squares with side length L/4 are removed from the plate.
(a) What is the xcoordinate of the center of mass?
= L/2
(b) What is the ycoordinate of the center of mass?

physics Only one part left !!!!!! PLZ HELP 
bobpursley,
Do this as two problems:
find the cg with the large plate, no corner cut, then the cg of the corner that is gone.
newCg*mass=oldCG*masscornercg*mass
where cg has to be figured in x, y coordinates.
