Here are presented a number of problems from the textbook
Analytical Mechanics by Grant R. Fowles (1962 edition)
This includes the 'chain sliding off the tabletop' problem
Problems from Chapter 7
This paper is an amplification of the problem of oblique collisions
which Fowles presented on pages 148--9. I also solved the problem of
of the elastic collision of two particles of equal mass.
