  I developed a program named Dynasim that is used for physics
simulation in a couple of Dutch polytechnics. Some included examples
adress this subject. If you send me an email request, i'll send you a
zip file with binaries and docs.

just one question :)

Is your program capable of simulationg situation where center of mass of 
the projectile is not on the axis of the rotation?
