    1. The problem statement, all variables and given/known data

    An Object A of mass M falls in a vertical plane under gravity. While it is in air, it breaks into two fragments, one having mass M/3 and the other having a mass of 2M/3. The center of mass of the broken fragments taken together shifts compared to that of the object A towards:

    a. the fragment with mass M/3
    b. the fragment with mass 2M/3
    c. Depends on the height of breaking
    d. Does not shifts
    e. None of the above

    2. Relevant equations

    summation Mx/x

    3. The attempt at a solution
