In WebAssign, always answer numerical questions with 3 significant figures.

CAUTION: Do not wait until the last minute to work and submit your WebAssign homework. It is a computer based system. Things go wrong with computers. I will not accept "computer problems" as an excuse for not being able to submit WebAssign homework on time. Many students submit WebAssign homework several days early. They have plenty of margin to deal with computer problems and plenty of time to get help..

HW due Wednesday August 22 (day 2) before class.

1. Bring a calculator to class for the math diagnostic test.

2. Purchase an iclicker (NOT the older CPS clicker which is still sold for some other classes but is being phased out) from the bookstore. Then, go to http://panda.unm.edu/clickers/ to obtain your Physics 151 id number, which the website calls your student id, which I call your “3 digit id” (although the first 99 students will not have 3 digits…more on this later). First select our class. Along with your first and last name (do NOT use all caps, just capitalize the first letter of each name), you will need enter your UNM ID number (Banner id) and you will also need to enter the iclicker serial number (found on the lower rear of the iclicker). The first student who goes to the site will be assigned the number 1, the second person will be assigned the number 2 etc. Don’t lose this number and please keep it private; you will use it the whole semester. You need to keep it private because I will use it to identify you when I post grades. You will use this number to identify yourself when you register for WebAssign and when you register your iclicker (use it for “student id” when registering your iclicker). You will also use this number (in the subject) when you email me and on tests, including, most important, the machine graded answer sheet. ( I call it a “3 digit id” even though it is not 3 digits for students 1 through 99 because you will need to fill in leading zeros on the test answer sheets to make it 3 digits. For example number 7 becomes 007.) After you have obtained your 3 digit id, use the link to go to the iclicker Website to register your iclicker. When you register your iclicker your student id is your 3 digit id (the id you just obtained from panda.unm.edu/clickers/).

3. Read the syllabus. You can find it online at panda.unm.edu, select classes then class homepages and then our course.
4. Purchase the text for the class, 6^th ed of Physics, Principles with Applications, by Giancoli.
5. Read the relevant pages in the text for the first 7 topics of the course (topics 1-7). See my “Inside Information” (found at Ereserves for topic information…the first few topics are on the pink sheet handed out the first day of class).

HW Due Friday August 24 (day 3) before class.
1. Purchase a WebAssign registration for the semester (see yellow sheet handed out in class for details).
2. Read about topics 8,9,10,11.
3. Work the following questions (Q) and problems (P). Chapter 1 Problems 9,18a. Chapter 3 Question 4, Problems 7,9a,10 . For problem 10 you should follow the approach I demonstrated in class: make a sketch of the vectors, make a table of components, sum the components, calculate the magnitude, calculate the angle, show the angle on a separate sketch and use 3 significant figures.

HW Due Monday August 27 (day 4) before class.
1. Read about topics 12-16.
2. Start on the homework due Wednesday.

HW Due Wednesday August 29 (day 5) before class.
1. Read about topic 19.
2. Work the following:: C2 Q 1,2,5,6,7,8,9,11,12,19,20 and C2 P 6,21,22 (assume the car is traveling in the positive x direction),24,25,26 . This hw is not handed in nor graded.

HW Due Friday August 31 (day 6) before class (and for WebAssign, before 11pm). (#1 on gradesheet)
1. Read about topic 25.
2. This is the first graded homework. It is due before 11pm on Friday August 31 on WebAssign. Go to WebAssign and work Chapter 2 P 33,34,35,36. You have 4 attempts to get the correct answer. I strongly advise you to start the assignment several days early. Most of the WebAssign hw is identical to the end of chapter hw from the text but with the numbers randomized. Each student will work the same general problem but with some of the numbers changed. I advise you to work problems from the book first (which are usually identical to the WebAssign problems except for some of the numbers). If you get the problems correct using the book numbers then you can be confident you will get the WebAssign correct. The odd answers are in the back of the book. If you ask me, I’ll give you the even answers during my office hours. If you do not work the assignment early then you are risking that computer or other problems (yours or WebAssign’s) will interfere with your work and cause you to miss the due time. I need to emphasize that no late hw is permitted. Another advantage to working several days early is that you will have time to get help if you are stuck. And, another advantage is that if you work on the problem before I discuss the material in class, you will get much more out of the class discussion.

HW Due Wednesday September 5 (day 7) before class. 1. Work the following. Chapter 2 Q 13 P 39,42,46,47 (for P 47 add part d , “Assume the height of the cliff is 121 m; how far below the top of the cliff is the stone at time 3.00 seconds? In addition, work another problem which I have made up; I’ll call it 47’. In 47’, rework P 47 parts “a” and “d” where the direction of the initial velocity is down (keep everything else the same). Also work Chapter 3 Q 9,19 and in Q 19 change the speed to 100 m/s. This hw is not handed in nor graded.
