I don't understand this problem I need help

In proton-beam therapy, a high-energy beam of
protons is fired at a tumor. As the protons stop in
the tumor, their kinetic energy breaks apart the
tumor's DNA, thus killing the tumor cells. For one
patient, it is desired to deposit 0.11 J of proton
energy in the tumor. To create the proton beam,
protons are accelerated from rest through a
1.2x104 kV potential difference.
