I've identified several mistakes on the key.
P 2 problem 5 The graph should be a straight line sloping up from the origin. I had made the position graph not the velocity graph.
p2. problem 8 part b The displacement should be 20m. I had accidentally used 20m/s instead of 30m/s.
p.4. The units for part b should be m/s^2

Keep the graph within the green band. Get ice cream. Avoid meteors.
Be the first to find out what happens when you get through all of the levels.

Making a UT QUEST Homework Account
Please go to this link
and start an online homework account. Click on "get started" and then
choose "I need a UT EID". In the next window choose "get a UT EID".
After you submit your information it will send your ID code to your
email account. With this code you will will sign in to my class and
start the first assignment. You may proceed to sign in now or bring
your EID code and password on Wednesday. On Friday we will log in as a
class, I will start accepting your enrollment and we will start the
first assignment.
This is how to sign in:
Return to the link above and log in.
You will then need to select a class based on a unique number. For Physics the unique number depends on your period. For per 2: 2232, for per 3: 2233, for per 4: 2234. Enter the number 223... and then select look up course info. Scroll down by clicking the arrow on the window that appears through the many other classes designated with that unique number until you find Physics (Grant High school 2012 Fall). It will probably be one of the last ones. Select it and then select request enrollment.
I will have to admit you into the class. The next time you log in, after I admit you, you will be able to use the "select course" and "select assignent" windows to start the Kinematics homework.

Unit 1: Kinematics in 1 Dimension
Goals:
1. Know and apply the definition for average velocity.
2. Know and apply the definition for average acceleration.
3. Differentiate instantaneous and average velocity.
4. Interpret graphs of position, velocity and acceleration, including through the use of slopes and the area under the graph.
5. Draw position, velocity and acceleration graphs for described motion.
6. Know the acceleration due to gravity.
7. Solve problems by using 5 basic mechanics equations.
8. Properly use sign conventions for positive and negative acceleration and velocity.
9. Describe sources of error as either random or systematic and suggest basic ways of reducing error such as controlling variables, doing multiple trials, collecting data over a wide range and using big sample sizes.

Homework: Due Date

Unit Test Thurs. 9/27
Welcome to Physics
The 2012-2013 school year has started. Welcome to Physics.
Here is some general information about how the class runs.
Grades:
Approximately 50% Tests, 30% Labs, 20% homework
Tests: About twice a quarter, with semester finals also. Retakes are available, but only half the missed points are recoverable.
Labs: Although we’ll have weekly hands-on lab assignments, I’ll only have you write up formal lab reports about twice a quarter. (The first one will be due Sept. 18.) Late labs are penalized at 10% a week.
Homework: Most homework will be submitted online through the web site https://quest.cns.utexas.edu/ It will be graded for accuracy, but on a generous scale because I recognize that homework is practice and created to find mistakes. Students who have difficulty getting internet access should talk with me. Accommodations will be found. No late homework accepted except for excused absences.
Grading Scale: 100-90 A, 90-80 B, 80-70 C, 70-60 D, 0-60 F.
Supplies:
Textbook
Notebook, or section of a notebook
Calculator
I hope you find the class challenging and fun.
