Homework 6 - Physics 150 Fall 2003
Due October 22, 2003
Remember that there are hints, worked exercise that covers several examples, and there are answers
to odd-numbered problems that are very similar to problems assigned.
- Question C, Ch. 8 of March.
- Question A, Ch. 9 of March. This is outlined in lecture and the text, but
here you are asked to state the procedure in your own words.
- Question B, Ch. 9 of March. Discuss the consequence and the relation
to Newton's ideas.
- Question E , Ch. 9 of March.
- The text (and lecture) give the argument that moving clocks run slow
based on the observation of light moving across a train. A crucial
step of the argument is that "both observers [in the train and on the ground]
agree on the width of the train." How you you know that they agree?
Is this just an extra assumption or is it required by the basic idea
of how one measures the width of an object perpendicular to the direction
of its motion?
- Ex. 1, Ch. 10. This is worked out in the solutions. Give the answer
also for v = 0.8 c.
- Ex. 2, Ch. 10. Give the answer for both v = 0.6 c and v = 0.8 c.
