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
