    Answer:

    K = 1800 kJ

    Explanation:

    Given that,

    The speed of the object, v = 30 m/s

    Mass of the object, m = 4000 kg

    We need to find the kinetic energy of the object. The formula for the kinetic energy is given by :

    K=\dfrac{1}{2}mv^2\\\\K=\dfrac{1}{2}\times 4000\times 30^2\\\\K=1800000\\\\or\\\\K=1800\ kJ

    So, the required kinetic energy is equal to 1800 kJ.
