        Explanation / Answer

        The first part (a) is half-way of the distance so (a) is 37.5 cm

        we need to attach each part at its center of mass.

        Part (b) will be 133*1 + 133 * 75 + 133 * (75 +37.5) all divided by 3 * 133 then subtract the first part (37.5).

        So. it is 27.33 cm

        Part (c) will be 133*1 + 133 * 75 + 133 * (75 +37.5) all divided by 3 * 133 then subtract the first part (37.5).

        So. it is 27.33 cm
