Practice Problems for Exam 2: Chapters 26-29 (Ch
29 sections 1-3 only)
This is a list of suggested practice problems in addition to
homework exercises. All numbers below refer to problems in Halliday,
Resnick and Walker, 10th edition. Q refers to the Questions section.
* designates a challenge problem. The answers to all odd-numbered
problems can be found in the back of the book, for you to check your
work.
WORKING ON THESE PROBLEMS IS A GREAT WAY TO DEVELOP YOUR FORMULA
SHEET FOR THE EXAM (single sided 8.5"x11"). If you look up any
equations or other information, write it on the sheet so that by the
end, you can work all the problems without looking at the
book. Note that the values of fundamental constants and
conversions will be provided on the exam. ALSO, if you feel like it
took a long time to solve a problem, take a look back when you are
done and see if you can find a simpler way to do it. This will help
when you are solving problems in limited time on the exam.
