Hi1315

Answer:

[tex]252J[/tex]

Explanation

Formula to find the kinetic energy is,

[tex] E_{k} = \frac{1}{2} m {v}^{2} \\ \\ m = mass(kg) \\ v = velocity( {ms}^{ - 1} )[/tex]

Lets solve

[tex] E_{k} = \frac{1}{2} m {v}^{2} \\ = \frac{1}{2} \times 14kg \times 6 {ms}^{ - 1} \times 6 {ms}^{ - 1} \\ = \frac{504}{2} \\ = 252J[/tex]

hope this helps you.
