    Answer:bowling ball has greater kinetic energy

    Explanation:

    Kinetic energy of bowling ball:

    mass=m=5kg

    Velocity=v=6m/s

    Kinetic energy = ke

    Ke=0.5 x m x v x v

    Ke=0.5 x 5 x 6 x 6

    Ke=90J

    Kinetic energy of ship:

    mass=m=120000kg

    velocity=v=0.02m/s

    Ke=0.5 x m x v x v

    Ke=0.5 x 120000 x 0.02 x 0.02

    Ke=24J
