A B D A person of mass 3M is standing on the left edge of a long, uniform board of mass M and length I that is floating in water, as shown in the figure above. The person walks slowly to the right edge of the board. The water exerts no drag forces on the board. The position of the center of mass of the board when the person is at the right edge of the board is (E) 5L/4 3L/4 L/4 3M -L/4 X 0 -L- M Board
