Question

I do not know how to solve the attached phyiscs question.

Part A
Proton-beam therapy can be preferable to X rays for cancer treatment
(although much more expensive) because protons deliver most of their
energy to the tumor, with less damage to healthy tissue. A cyclotron
used to accelerate protons for cancer treatment repeatedly passes the
protons through a 15-kV potential difference.
How many passes are needed to bring the protons' kinetic energy to 1.5 x 10-11 J?
