The first three problems constitute the re-take for the exam. It is not exactly the same, so don't work from the exam itself, but rather refer to this and the indicated problem in the course text. Submit this separately from the "regular" homework listed below.

- 2.31, do all three parts from the book and also do part three as it was written on the exam.
- Do problem 2 on the exam, but with one important difference: use F(t)=k_p(x_d - x(t)), which has the opposite sign of what was on the exam.
- 3.29, do all 27 from the book, not just 13 like you had to do on the exam.

Exercises: from the course text, 5.3, 5.4 ad 5.7.
