PHYSICS 321 - Classical Mechanics I

Spring 2010

Homework Set #3 (due 2/3/10)

1. Thornton and Marion, problem 9-4.

2. Thornton and Marion, problem 9-8.

3. Thornton and Marion, problem 9-9.

4. Thornton and Marion, problem 9-12.

5. Thornton and Marion, problem 9-37. Attempted clarification: the force is F = 360 – 10⁷t² with F in Newtons, t in seconds (and so the units of the constant 10⁷ are, of course, in N.s^-2). Hint: Start by finding the time at which the force becomes zero.

6. Thornton and Marion, problem 9-54.

7. Thornton and Marion, problem 9-55. Just calculate the maximum velocity; ignore the
last sentence in the question.
