Classical Mechanics Problems (CMP) is a source book for instructors of advanced classical mechanics at the Goldstein level. The book is available in electronic form to instructors by request to the author. It is free courseware and can be freely used and distributed, but not used for commercial purposes. The problems are grouped by topics in chapters: see Contents below. The chapter ordering follows the Goldstein chapter/topic ordering. For each chapter there are two classes of problems: in order of appearance in a chapter they are: (1) multiple-choice problems and (2) full-answer problems. Almost all the problems have complete suggested answers. The answers may be the greatest benefit of CMP. The problems and answers can be posted on the web in pdf format. The problems have been suggested mainly by Goldstein problems, but have all been written by me. Given that the ideas for problems are the common coin of the realm, I prefer to call them redactions. Instructors, however, might well wish to find solutions to particular problems from well known texts. Therefore, I give the suggesting source (when there is one or when I recall what it was) by a reference code on the extra keyword line: e.g., (Go3-29.1) stands for Goldstein (3rd Edition), p. 29, problem 1. Caveat: my redaction and the suggesting source problem will not in general correspond perfectly or even closely in some cases. The references for the source texts and other references follow the contents. A general citation is usually, e.g., Ar-400 for Arfken, p. 400. At the end of the book are two appendices. The first is an equation sheet suitable to give to students as a test aid and a review sheet. The second is a set of answer tables for multiple choice questions. Classical Mechanics Problems is a book in progress. There are gaps in the coverage and the ordering of the problems by chapters is not yet final. User instructors can, of course, add and modify as they list. Everything is written in plain TEX in my own idiosyncratic style. The questions are all have codes and keywords for easy selection electronically or by hand. A fortran program for selecting the problems and outputting them in quiz, assignment, and test formats is also available. Note the quiz, etc. creation procedure is a bit clonky, but it works. User instructors could easily construct their own programs for problem selection. I would like to thank the Physics Department of New Mexico Tech for its support for this work. Thanks also to the students who helped flight-test the problems.
