[QUOTE="kristjan, post: 6033713, member: 646778"] [h2]Homework Statement [/h2] The moving proton hits the second proton, which we consider to be stationary. In the moment of central strike gap between the protons is 10(-13)m. What was the initial speed of the moving proton? Proton mass is 1.67*10(-27)kg and charge 1.6*10(-19) C. [h2]Homework Equations[/h2] Electric potential energy U=kQq[B]/[/B]r Kinetic energy 1/2 mv2[h2]The Attempt at a Solution[/h2] kinetic energy is transformed into electric potential energy at the point of closest approach: electric potential energy=kinetic energy of moving proton From there I find initial speed of moving proton to be v=1.66*10(6) m/s, in book answer is 2.35*10(6) m/s [/QUOTE]
