Answer:

320 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 40 \times {4}^{2} \\ = 20 \times 16[/tex]

We have the final answer as

320 J

Hope this helps you
