This text is aimed at upper-level students in physics, engineering and other sciences. Its subject, modern classical mechanics, is useful for courses in physics, as well as a variety of industrial and commercial applications involving the design of moving equipment in the automobile, aerospace, and control device industries. The author has included useful computer exercises in which readers must find graphically represented results to linear and non-linear problems. An extensive appendix on computer methods using Fortran and Mathcad makes this work particularly suitable.
