Unformatted text preview: A M Kolchin/ SAR Physics Also available at: www.phys.ufl.edu/˜ kolchin/SAR physics/HW6 Homework 6 Due Wednesday October 4, 2006 (Worth 3 homeworks) • PART I. In this part of the assignment: 1. You will analyze the motion of a bicycle using kinematics. Work through the assignment step by step. 2. all graphs must be done on graph paper ; otherwise the assignment will not be accepted. 3. Use the following symbols: Let t =time since the bicycle started moving ( s ). Let x ( t ) =position of the bicycle ( m ) Let v ( t ) =velocity of the bicycle ( m/s ) Let a =acceleration of the bicycle ( m/s 2 ) Suppose you start from rest at this building on your bicycle and accelerate at a constant rate up to a velocity of 10 m/s over a time interval of 5 s headed east. Use the building where x = 0 m , v = 0 m/s , t = 0 s as your reference point. 1. What is your acceleration? (Show an equation, and show all units.) continue to next page .... 1 2. Graphing acceleration vs. time and inferring its implications ....
