Answer:
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 1500 \times {40}^{2} \\ = 750 \times 400 \\ = 300000 \\ \\ \\ \\ = 3.0 \times {10}^{6} \: \: joules[/tex]
Hope this helps you
