Colorado at Boulder 1/10/2010 1 Physics 2010 -- Spring 2010 Recitation Assignment 2 NAME ________________________ Section Day (circle): M Tu W Th F Section Time: 8a 10a 12p 2p 4p Your TA________________________ Instructions: Work in groups of 3 to 4. Use the space provided. Plots should be drawn neatly, with axes and units clearly labeled. This week's assignment will focus on vectors (Ch. 3). 1. You are walking around Physton, a city with a rectangular street grid. North-south blocks are 0.2 km long, and east-west blocks are 0.3 km long. You walk seven blocks east, one block north, two blocks east, and six blocks south. a) Using pencil, use vectors to draw the path. Remember that each vector needs a single arrowhead to show its direction. What is the scalar distance your feet have traveled? b) On your sketch above, use dotted lines to show the vector components of the displacement vector. What are the magnitudes of the vector components of your displacement? (Consider north to be the y axis and east to be the x axis.) c) Use a bold line to show the displacement on your drawing in part a. What is the magnitude of the displacement from your starting point to your end point? (i.e. how far are you "as the crow flies"?) d) Which of the above quantities would be an indicator of how tired you are? d) Which of the above quantities would be an indicator of how tired you are?...
