Answer:
54.68 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 15 \times {2.7}^{2} \\ = 7.5 \times 7.29 \\ = 54.675[/tex]
We have the final answer as
54.68 J
Hope this helps you
