 2: T 10/2, 5: T 10/2, 7: T 10/2Open-lab-notebook QUIZ Today!  You'll be able to use anything that is in (and attached to) your lab notebook and nothing else.  No loose papers allowed.  After the quiz, we'll finish working on Unit 2 Worksheets page 1.  I will be circulating to answer your question.  Here you are learning to manipulate mathematical models (equations) as well as graphical models for kinematics.  Then, we'll discuss how we can get your kinematics equations from your x vs. t and v vs. t graphs.  (see presentation below.)If there's time, we'll do some more practice problems in small groups - Chapter 2 #20. 21. 33-36, 44, 48, 54-58, 77.  Work on your collaborative team member skills.  If you can do these problems and Unit 2 Worksheets page 1, you should be good for the test.Presentation:  Deriving Kinematics Equations from GraphsHomework:   Test on Kinematics next Monday, October 8th.  We will start new material before then.  If you have not finished Unit 2 Worksheets page 1, finish working on it.  ANSWERS.   FULL SOLUTIONS.Answers to evens:  20. 59.9 mi/h, No34.  (a) 0 m/s2, 4.0 m/s2, -4.0 m/s2, 8.0 m/s2, 0 m/s2   (b) Constant velocity of -4.0 m/s36. 150 s44.  (a) 25 m   (b) car B48.  10.5 m, Yes54.  7.1 m/s56.  (a) (3) 4x   (b) 6.75 m58.  (a) 30.4 m/s   (b) 166 m   (c) 7.44 s
