Posted on by

Classical Mechanics Homework Assignment #4, due by 5 pm Monday October 10 to Krishna’s office Lab 2 3255. All problems from Taylor except as indicated.

  1. 3.19
  2. 3.35 (see note below)
  3. 3.36
  4. 4.2
  5. 4.4 (see note below)
  6. 4.8 (I would have called this a *** problem) Problem 4.8 is cancelled as a homework problem. It is available for a public solution, should someone wish to choose it.

Note for 3.35: In order to roll without slipping, there must be friction; in this case it’s rolling friction (this is mentioned in part (c) but you need this for part (a)).

Note for 4.4: Make sure to justify why Γext is zero even though there is a tension in the string.
