Note that odd exercises and problems have answers in the back of the textbook. Please do the problems on Mastering Physics by logging in with your userid and password.

Please note the Mastering Physics has system requirements and math requirements for the entering of expressions. And I've cut and pasted formula/symbol entry help pages here for your reference.

- An object is moving with SHM of amplitude A on the end of a spring. If the Amplitude is doubled, what happens to the total distance the object travels in one period? What happens to the period? What happens to the maximum speed of the object? Discuss why these results are related.

- A pendulum is mounted in an elevator that accelerates upward with constant acceleration. Does the period increase, decrease, or remain the same? Why?

- If a uniform spring is cut in half, what is the force constant for each half? Why? How would the frequency of SHM using a half-spring differ from that of a similar mass oscillating on the entire spring?

Additional Discussion Questions: (Please turn in written answers to these at the start of class.)
Drop a solid sphere of aluminum into a bucket of water sitting on the ground. The buoyant force equals the weight of the water displaced, which is less than the weight of the sphere, so it sinks to the bottom. If you take the bucket with you on an elevator that accelerates upward, the apparent weight of the water increases and the buoyant force on the sphere increases, too. Could the acceleration of the elevator be great enough to make the sphere pop up out of the bucket of water? Explain!

You are floating in a canoe in the middle of a swimming pool. Your friend as at the edge of the pool, carefully noting the level of the water on the side of the pool. You have a bowling ball with you in the canoe. If you carefully drop the bowling ball over the side of the canoe, and it sinks to the bottom of the pool, does the level of the water in the pool rise or fall?

Our Course ID is CHABOTPHYSICS4CSPRING2011. If you haven't purchased your book and access code in the bookstore yet, you must email me or contact me. You can use the default username of "physics4cstudents" and password of "spring2011" to LOOK at the problems, but you'll have to write down the answers on paper, and turn those in by the due date for credit, and once you buy the code, I'll adjust your score.
