    The question is incomplete since no table is provided. However, I looked into other references to find the table.

    The given are:

    Autumn Mass = 50 kg Velocity = 4 m / s

    Mohammed Mass = 57 kg Velocity = 3 m / s

    Lexy Mass = 53 kg Velocity = 2 m / s

    Chiang Mass = 64 kg Velocity = 5 m / s

    For us to be able to answer this, let us calculate the Kinetic Energy of each person using the formula:

    KE = 0.5 m v^2

    Autumn:

    KE = 0.5 * 50 kg * (4 m / s) ^2 = 400 N

    Mohammed:

    KE = 0.5 * 57 kg * (3 m / s) ^2 = 256.5 N

    Lexy:

    KE = 0.5 * 53 kg * (2 m / s) ^2 = 106 N

    Chiang:

    KE = 0.5 * 64 kg * (5 m / s) ^2 = 800 N

    Therefore from the choices, the answer is:

    Mohammed has less kinetic energy than Autumn.
