Problem 27.

Two bricks are placed on a meter long wooden board. Brick #1 is placed 11.2 cm from the left end of the board and has a mass of 3.44kg. Brick #2 is placed 77.0 cm from the left end of the board and has a mass of 2.5 kg. The 1-meter long board has a mass of 0.4 kg. Find the center of mass of the system. Sketch and label a figure
