Ch10 HW1 (Homework) BRANDON JARROTT FELDKAMP PHYS 2211, section M, Fall 2008 Instructor: Jennifer Curtis Web Assign Current Score: 30 out of 30 Due: Monday, November 3, 2008 09:00 AM EST Description Angular momentum; Conservation of angular momentum Instructions Reading: Section 10.1 and Section 10.4 On this assignment you are allowed 3 submissions per question part. The due date for this assignment is past. Your work can be viewed below, but no changes can be made. 1. [MI2 10.X.01.alt01] 8/8 points Determine both the magnitude and direction of the translational angular momentum of the particle at location O relative to each point: A , B , C , D , E , F , G , and H . The magnitude of the momentum p = 30 kg·m/s, and the distances are h = 8 m, b = 5 m, and w = 7 m. Assume the usual coordinate system ( +x to the right, +y up, and +z out of the page, toward you.) | A | = 5*30 150 kg · m 2 /s Direction: -z -z | B | = 30*5 150 kg · m 2 /s Direction: -z -z | C | = 0 0 kg · m 2 /s Direction: none (zero magnitude) none (zero magnitude) | D | = 8*30 240 kg · m 2 /s Direction: +z +z Ch10 HW1 http://www.webassign.net/[email protected]/student.pl?l=2008. .. 1 of 6 11/18/2008 6:26 PM
