I need help for the following problem:(adsbygoogle = window.adsbygoogle || []).push({});

Two alpha-particles (diameter 1.9 x 10^-19 m) are headed directly toward each other with equal speeds. Compute the minimum energy in electron volts each particle must have if they are to collide. What inital speed must each particle have?

For the initial speed, i know that i need the work energy theorem. However, i don't know how to get the work. Thanks.
