Answer:
411.86 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 55 \times {3.87}^{2} \\ = 27.5 \times 14.9769 \\ = 411.86475[/tex]
We have the final answer as
411.86 J
Hope this helps you
