CHAPTER 1

For problems 35 through 44, draw a complete diagram and a pictorial representation. Do not solve these problems or do any mathematics.
  1. (P.33 Prob.38) A speed skater moving across frictionless ice at 8.0m/s hits a 5.0-m-wide patch of rough ice. She slows steadily, then continues on at 6.0m/s. What is her acceleration on the rough ice? Draw a complete diagram and a pictorial representation. Do not solve this problem or do any mathematics.
  2. (P.34 Prob.46) Write a one or two sentence "story" about a real object that has this motion diagram. Your stories should talk about people or objects by name and say what they are doing.

  3. (p.34 Prob.54) (a) Complete the motion diagram by adding acceleration vectors. (b) Write a physics problem for which this is the correct motion diagram. Be imaginative! Don't forget to include enough information to make the problem complete and to state clearly what is to be found. (c) Draw a full pictorial representation for your problem.
