    B) True

    E) True

    Explanation:

    As we know that the total mechanical energy is summation of potential energy and kinetic energy.

    A) False

    This statement is false because it say that all kinetic or all potential energy. This should not be all.

    B) True

    When dissipative interactions occurs then the total mechanical energy of the system can not be constant. But if nondissipative interactions occur then the total mechanical energy of the system is remain constant.

    C) False

    When dissipative interactions occurs then the total mechanical energy of the system can not be constant. But if nondissipative interactions occur then the total mechanical energy of the system is remain constant.

    D) False

    This is not true because we know that total mechanical energy is summation of potential energy and kinetic energy. But does not tell that it will be equally divided between kinetic and potential energy.

    E) True

    Yes it is true because the mechanical energy can be converted in to heat energy due to friction force.
