Answer:

343 J

Explanation:

The kinetic energy of an object can be found by using the formula

[tex]k = \frac{1}{2} m {v}^{2} \\ [/tex]

m is the mass

v is the velocity

We have

[tex]k = \frac{1}{2} \times 14 \times {7}^{2} \\ = 7 \times49 \\ = 343 \: \: \: \: \: [/tex]

We have the final answer as
