Explanation:
See attachment below.
The picture is very blurry I wish I could help
The kinetic energy of an object is given by:

where m is the mass of the object and v its speed. The ball in this problem has a mass of m=0.2 kg and a kinetic energy of K=40 J, so we can rearrange the previous equation to find its speed:

The process of making a heavy (single (a part of an atom) from two lighter than the original nuclei n<span>uclear is commonly known as the Nuclear Fission. It is called a nuclear reaction, due to it realizes a huge about of energy.</span>
