Phys116 Problem Set 3 Due: Friday, Sept. 19, 2003 before the start of class. Please write your TA’s name at the top of your solution set. Communicate your reasoning in your solutions, concisely and clearly. Efforts are as important as correct answers. 1. We have emphasized the importance of using an inertial reference frame when applying Newton’s laws. Suppose you wish to carry something around with you to determine whether your personal reference frame is accelerated. Draw a picture and describe the operating principle of some tool or mechanism that you might use to determine whether you are accelerating in a horizontal direction. It does not need to be complicated or particularly sensitive, and there are many possible correct answers.

Unformatted text preview: The device should be able to operate when you are isolated in a room without any means of contact with the outside world. 2. K&K problem 2.5. 3. K&K problem 2.6. 4. K&K problem 2.11. 5. K&K problem 2.29. 6. K&K problem 2.16. As always, use an inertial reference frame. Note that Example 2.4 on page 74 will be helpful in setting up this problem. 7. K&K problem 2.28. (Hint: What is the direction of the frictional force in solving for the condition of minimum speed? For the maximum speed?) If you feel adventurous, many of the other problems at the end of chapter 2 are excellent. A few more will be assigned next week....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
