MasteringPhysics: Assignment Print View http://session.masteringphysics.com/myct/assignmentPrint?assignm... 1 of 14 11/18/07 7:34 PM [ Print View ] physics 2211 MP14: Chapter 14 Due at 5:30pm on Sunday, November 25, 2007 View Grading Details Position, Velocity, and Acceleration of an Oscillator Learning Goal: To learn to find kinematic variables from a graph of position vs. time. The graph of the position of an oscillating object as a function of time is shown. Some of the questions ask you to determine ranges on the graph over which a statement is true. When answering these questions, choose the most complete answer. For example, if the answer "B to D" were correct, then "B to C" would technically also be correct--but you will only recieve credit for choosing the most complete answer. Part A Where on the graph is ? ANSWER: A to B A to C C to D C to E B to D A to B and D to E Part B Where on the graph is ? [ Print ]

Hint I.1 How to tell if Hint not displayed ANSWER: A only B only C only D only E only A and C A and C and E B and D Harmonic Oscillator Acceleration Learning Goal: To understand the application of the general harmonic equation to finding the acceleration of a spring oscillator as a function of time. One end of a spring with spring constant is attached to the wall. The other end is attached to a block of mass . The block rests on a frictionless horizontal surface. The equilibrium position of the left side of the block is defined to be . The length of the relaxed spring is .
