Chapters 1 − 17

, PREFACE for Volume I
This volume contains the answers to the Focus on Concepts questions and the
complete solutions to the problems for chapters 1 through 17. These chapters
include all of mechanics (including fluids), thermal physics and wave motion. The
solutions for chapters 18 through 32 (electricity and magnetism, light and optics,
and modern physics) are contained in Volume 2.

Each chapter is organized so that the answers to the Focus on Concepts questions
appear first, followed by the solutions to the problems.

An electronic version of this manual is available on the Instructor’s Companion
Website. The files are available in three formats: Microsoft Word
97-2003, Microsoft Word 2007, and PDF files of each individual solution.

The icon SSM at the beginning of some of the problems indicates that the
solution is also available in the Student Solutions Manual.
