For each assignment, one problem will be worth a maximum of 10 points, and the remaining problems will be worth a maximum of 1 point (which is common in the Physics 1-5 sequence for large class sizes). Unfortunately, no late homework can be accepted, except in cases of illness (with doctor's note) or family emergency. For full credit on homework assignments, you must:
Please note that the grader, Matt Hansen, will grade your homework, not the instructor. Homework will be returned in lecture, but you can also view your scores online by logging onto the classweb system. If you have questions about your homework score, please follow these three steps:
2. Exercise 10-2
3. Exercise 10-14 (See Table 9-2 for the moment of inertia of a rod.)
4. Problem 10-69 (Please use energy methods to solve this, rather
the methods of section 10-3.)
5. Exercise 10-37
6. Exercise 10-42
1. Exercise 12-11
2. Exercise 12-15
3. Exercise 12-29
4. Problem 12-63 (There is enough data to use conservation of
energy, but not angular momentum.)
5. Exercise 12-37
Extra Credit (2 points): Problem 12-42
Hints:
(b) The center of mass and center of gravity here are for the two large
spheres, not all three spheres.
(c) See note for (b). By definition, the center of gravity is
a single point where the gravitational force can be taken to act, so can
this force ever produce a torque about this point?
1. Exercise 13-11
2. Exercise 13-21
3. Exercise 13-23
4. Exercise 13-41
5. Exercise 13-43
Extra Credit (2 points): Exercise 31-35
This is a plug-in from Chapter 31 to illustrate the SHM exhibited by
the LRC circuit introduced in class.
2. Problem 14-55
See Table 14-1 for the densities of water and mercury.
3. Exercise 14-15
See Table 14-1 for the density of water.
4. Exercise 14-36
Consider the two points to be at equal elevation
(y1=y2 in equation 14-21). Also
see equation 14-14.
5. Problem 14-90
(a) The "discharge rate" is just the volume flow
rate of equations 14-14 and 14-15.
(b) Consider the two points to be at equal elevation,
as in Exercise 14-36 above.
(c) You can use the result of (b), more hints about
this will be given in class on Thursday, July 11.
Also see Table 14-1
for the densities of water and mercury.
2. Exercise 15-49
3. Problem 15-91
4. Exercise 15-62
5. Exercise 15-63
6. Exercise 15-66
Extra Credit (2 points):
Challenge Problem 16-77
The following parts will not be graded:
(a) and (b): will be discussed in class on Tuesday,
July 23.
(g): see the values given in the back of the book.
1. Information about the final exam will be posted at:

Visit and read the contents of this link (keep visiting
it regularly for any updates).
Note: you must bring a photo ID to the final exam.
2. Exercise 17-26
3. Problem 17-31
4. Problem 17-38
Here are some hints:
(a) Just consider thermal expansion.
(c) Use heat capacity.
(e) Compare your results from (b), (c), (d).
5. Problem 17-45
6. Problem 17-50
