A square block, a rectangular block, a triangular block, and a quarter circle block are arranged as shown
below. A smaller square chunk was cut from the square block, leaving a hole in the figure. Find the center
of mass of the composite figure. Use the axes provided as reference for the origin (0, 0).
Square: L units x L units, mass = m
Rectangle: (L/2) units x 2L units, mass = 3.5 m
Quarter circle: radius = (L/2) units, mass = 5 m
Triangle: height = L units, base = (L/2) units, mass = 0.75 m
Square hole: L/2 units x L/2 units
