Physics 2D, Fall 2000, Homeworks

This page has homework assignments and solutions. They are all from the course textbook, Serway et al, 2nd ed.
Please don't look at the solutions until after you make a serious effort to solve the problems on your own.

First week (9/25): Chapter 2 problems:

Problems # 3, 4, 5, 11, 14, 16, 17, 24, 28, 29
Solutions:
Section 2.2 problems (PDF Format)

Fourth week (10/16): Chapter 5 problems:

Problems # 2, 10, 11, 13, 16, 25, 26, 32, 33, 34, 35, 36
(note: problem 2 was added)
Solutions: (There are some problems with the solutions (sorry about it), see below):
Problem 2
Problems 10-16 (PDF Format)
Rest of them (except 36) (PDF Format)
Problem 36
1) Problem 2 solution is off by a factor of 2, answer is 41% (when squaring A, a factor of 2 was omitted).
2) Problem 11: should be (x+L/2) instead of (x-L/2) in wavefunction. It doesn't change the answers however.
3) Problem 16: to calculate the probability a ratio of two integrals is taken. This may look confusing but is actually correct: it is equivalent to first calculating the normalization constant A and then writing P as a single integral.

Fifth week (10/23): Chapter 6 problems:
