sweet-ann [11.9K]

Answer:

<h2>411.86 J</h2>

Explanation:

The kinetic energy of an object can be found by using the formula

k =  \frac{1}{2} m {v}^{2}  \\

m is the mass

v is the velocity

From the question we have

k =  \frac{1}{2}  \times 55  \times  {3.87}^{2}  \\  = 27.5 \times 14.9769 \\  = 411.86475

We have the final answer as

<h3>411.86 J</h3>
