Unformatted text preview: Physics 2E3 Mar 16, 2010 Name_________________________________ Student Number:________________________ Duration: 80 minutes Only the McMaster standard calculator ( Casio fx-991 ) is allowed. Notes and formula sheets are not permitted. A sheet of formulae and information isincluded as the last page; if you use it, it is your responsibility to know what the formulae mean and when they can be used. Most of the formulae may not be useful for any of the questions. You may write in pen or pencil. Assume numbers given are exact, and calculate numerical answers to at least 2 significant digits. There are 8 questions and 9 pages, including two blank pages for extra answer space if needed, and a formula sheet at the end. Make sure your paper is complete. Unless otherwise noted, complete solutions with brief, clear explanations are required for full marks. 1 (2) 2 (2) 3 (2) 4 (2) 5 (2) 6 (2) 7 (6) 8 (7) Total (25) Page 2 of 9 For the multiple-choice questions, circle the best or most nearly correct answer. No solution is required if the answer is correct. Half marks may be given for a clear solution that is partially correct, even if the answer is wrong. 1. (2 marks) For the damped oscillator, bv kx F-- = , we couldn’t use the lagrangian method to generate a differential equation of motion because: A) the system had too few degrees of freedom....
