Answer:
250 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 125 \times {2}^{2} \\ = \frac{1}{2} \times 125 \times4 \\ = 125 \times 2[/tex]
We have the final answer as
250 J
Hope this helps you
