HW 13

OOOOOPS

Homework 13 for morning section 0001 was inadvertently set to expire at 9:30 AM, instead of the usual 10:30 AM. My error. I will rectify this over the weekend... extra practice for the exam.

Afternoon section 0002, you guys should be OK.

Another bonus podcast

I am going to create a new bonus podcast for you, with corresponding homework, by the weekend. If you have not gotten onto the iTunes U active list yet, better get hustling.

New iTunes U bonus

I just uploaded a bonus point for 112 more students.

So far, morning section 0001 is ahead, which means that, if we execute the secret Friday plan, it would be section 0001 that gets first dibs.

	Section 0001	Section 0002
on iTunes U	131	75
on iTunes U (%)	0.642	0.581
slackers	73	54
slackers (%)	0.358	0.419

You guys in section 0002, you had better get hustling.

Next iTunes U bonus points update will be Tuesday next week.

L21 and HW

I just finished uploading L21 data from yesterday. Plus, I did some housekeeping in the My Grades page, so HW and CPS numbers ought to be spiffed up properly.

Doc cam files and CPS study guides are squared away.

This morning, I am going to look at the iTunes U weekly usage spreadsheet, which I received last night. I sift out the NIDs in our two lecture sections and use the NIDs to verify your activity. I will see which section is closer to our secret Friday plan. Your iTunes bonus point might be updated today.

Homework 13 ready

Your next homework assignment, #13, will go active at 4:20 PM this afternoon. I will be due at the normal times on Wednesday.

Note: several of the exercises in this HW are calculations, so the numeric data given changes each time you take it. I have set the number of attempts to UNLIMITED, so that you can practice on all the various data combinations until you feel super confident.

Homework 12 with a real brain burner about conservation ot total mechanical energy

Your homework #12 is now UP, due Monday at the usual time. It contains some basic exercises and then a brain burner concerning Fig. 7-12. Read carefully.

Since the brain burner, question 6, is a real tough one, I am giving you unlimited attempts. Remember, the brain burner has different values for the physical quantities each time you attempt it, so read carefully. You can use it for practice with each new value.

Final note: Read carefully!

iTunes U updated; classwork and homework

I will try to work on Exam 1 odds and ends tonight.

For now, your visual podcast of Wednesday's lecture is up in iTunes U. Also, I have updated miscellaneous homework and CPS data in your My Grades page in Webcourses.
