    M = 1200 kg, the mass of the boat and its occupants

    v = 1.8 m/s, the speed of the boat

    The KE (kinetic energy) of the boat is

    KE = (1/2) * m*v²

    = 0.5 * (1200 kg) * (1.8 m/s) ²

    = 1944 J

    To stop the boat, the work done should be equal to the KE of the boat.

    Therefore the work done is 1944 J.

    Answer: 1944 J
