(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Two protons that are very far apart are hurled straight at each other, each with an initial kinetic energy of 0.16 MeV, where 1 mega electron volt is equal to 1x10^6 multiply (1.6x10^-19) joules. What is the separation of the protons from each other when they momentarily come to a stop?

2. Relevant equations

Ue = (1/4[tex]\pi[/tex][tex]\epsilon[/tex])((q[tex]_{1}[/tex]q[tex]_{2}[/tex])/r)

E[tex]_{f}[/tex] = E[tex]_{i}[/tex] + W

3. The attempt at a solution

I am very confused on how to get this problem started, especially since they give the kinetic energy. I tried to manipulate the kinetic energy formula ((1/2)mv^2) but I am still really confused on how to approach this problem.
