Unformatted text preview: Physics 105: Mechanics Fall 2009 Homework 7 Due Friday 10/23 Read sections 5.8-5.16 the text. Do the following problems. 1. Do 5.RQ.51. 2. Do 5.RQ.55. 3. Do 5.P.57. 4. Do 5.P.61. 5. Do 5.P.62. 6. Do 5.P.69. 7. Do 5.P.78. 8. Do 5.P.79. 9. In problem 8 of HW 6, you analyzed the parallel and perpendicular components of the rate of change of the momentum of a pendulum on the up swing part of its trajectory, at a position where the string makes an angle θ to the vertical. In that problem, you were told the speed of the bob when it was at the position of interest. Here you will calculate that speed, given initial conditions. L v θ A θ B B A v =0 A B The pendulum bob is released from rest at position A. Let the SYSTEM be the bob. (a) What objects in the SURROUNDINGS interact significantly with the bob? (b) For each object in the SURROUNDING, determine the work done by that object on the bob as the bob travels from A to B....
