...it's the so called leap-frog verlet algorithm.
For easy-to-read sample code, try
http://www.mpikg-golm.mpg.de/th/physik/allen_tildesley/al_tild.html
and follow the links.
In addition, you could feed your favorite search engine combinations
of 'verlet' and 'frog', 'velocity', 'position', 'symplectic',........
and see where that gets you (quite far, if you want).
hope it helps,
regards
Andreas
