Answer:

Mass of the polar beer is 380.2 kg

Explanation:

As we know that kinetic energy is given as

[tex]K = \frac{1}{2}mv^2[/tex]

now we know that

[tex]K = 23000 J[/tex]

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

now we have

[tex]23000 = \frac{1}{2}m(11^2)[/tex]

[tex]m = 380.2 kg[/tex]
