Today, we'll look at vertical circles where gravity combines with some other force to account for the centripetal force.

HandoutHard Circular Motion Problems.  (skip #9) ANSWERS.
HomeworkTest corrections for Unit 4 test due Tuesday, January 12.  Do Hard Circular Motion Problems - note: for #3a, an acceleration of “1g” is 9.8 m/s2, so an acceleration of 0.050g is (0.050)(9.8 m/s2).  Then do #1, 2, 3, & 5 from Even Harder problems from next post.  If you need extra practice on easy UCM problems, Circular Motion Practice worksheet (optional) (Ans:  1. (a) 8.77m/s2 (b) mass times 1a.  2. (a) 1.56m/s (b) mass times 8.11m/s2(c) 8.11m/s2.  3. (a) 0.650 (b) no change.
