Here are the 14 friction problems that are due for tomorrow:

  1. pages 1-3, #'s 7, and 14 to 17. Remember there are answers to these problems in your packet so you can check your work. Important: the answer to #17 is wrong. It should be 6 m/s/s
  2. Concept-Development Practice Page (CDPP) 5-1, pages 37, 38, and 47, Exercises 7 to 11, and A-6 to A-8. The answers to these problems are: Exercise 7 = 102 N, Exercise 8 = 350 N, Exercise 9a = 78 N, Exercise 9b = Yes, Exercise 10 = 0.1, Exercise 11a = 0.2, Exercise 11b = higher coefficient of friction, A-6 = 24 N, A-7 = 0.2, A-8 = 1070 N
