Answer:
896,000 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 1120 \times {40}^{2} \\ = 560 \times 1600[/tex]
We have the final answer as
896,000 J
Hope this helps you
