marissa [1.9K]

Answer:

<h2>6 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 3 \times  {2}^{2}  \\  =  \frac{1}{2}  \times 3 \times 4 \\  = 3 \times 2

We have the final answer as

<h3>6 J</h3>

Hope this helps you
