Answer:

64 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

From the question we have

[tex]k = \frac{1}{2} \times 8 \times {4}^{2} \\ = 4 \times 16[/tex]

We have the final answer as

64 J

Hope this helps you

the answer to your question is 200 J
