*25. mmh Two protons are moving directly toward one another. When they are very far apart, their initial speeds are 3.00 x 106 m/s. What is the distance of closest approach?

 

As the two protons approach each other, the potential energy rises.  The distance of closest approach is the distance at which all the initial kinetic energy is transformed to potential energy.
