ANSWERS TO EXERCISES IN
Page 2 PREFACE
What follows are answers to the exercises in BASIC PHYSICS, identi-cal except for a few small changes to the answers provided for the use of instructors shortly after the book’s 1968 publication. The changes are the addition of a Table of Contents, altered style for headings, and one altered page reference in the answer to Exercise 15.6 to reflect changed pagination in the 2017 version of the book. These answers may still be of some interest to teachers who buy and use the reissued book.
The reissued book is published by World Scientific. This Manual is provided by H Bar Press. It has been prepared by Adam B. Ford.

In most of the exercises requiring numerical calculation, numbers have been chosen to be physically meaningful, rather than to lead to elementary arithmetic. Students should therefore be encouraged to develop skill in using the slide rule for multiplication and division. Most numerical answers are given here to three significant figures, although two figures are usually quite sufficient in students’ answers.
We have worked hard to reduce errors in this manual to a low level. Undoubtedly a few remain. The author will be most grateful to instructors who call attention to any wrong answers or ambiguous questions.
This manual was prepared by Kenneth W. Ford with the assistance of Harris Benson, David Tang, and John Williams.
