Announcements

• Hand Back Exam 1
• For the most part, your responses to questions
  1-5 were good.
• For the most part, points lost were not because
  you said things that were wrong, but because you
  didnt say enough (avoided the key thing(s))
• Question 6 had mixed results.
• Best solution adds a Bounce() method to move() in
  BoundedBall, although you can also do with
  setMotion() or with a CAREFUL check of boundaries
  in move() of the FBB.
• Several of you missed part B
