    Answer:

    Mass of the polar beer is 380.2 kg

    Explanation:

    As we know that kinetic energy is given as

    K = \frac{1}{2}mv^2

    now we know that

    K = 23000 J

    also we know that the speed of the beer is 11 m/s

    now we have

    23000 = \frac{1}{2}m(11^2)

    m = 380.2 kg
