Answer:
18.51 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 2.55 \times {3.81}^{2} \\ = 1.275 \times 14.5161 \\ = 18.5080275[/tex]
We have the final answer as
18.51 J
Hope this helps you
