Try to make the graph shown in "Thinking About the Question". Refer to Technical Hints to see how to set up the walking track. Set the axis to 60 seconds. Set the distance to the length of your track. Refer to Technical Hints on how to run the sonar ranger software. Did you predict the right direction to move away from the sonar ranger? Did your speed change during the your walk?
Investigate the following motions on your track with the sonar ranger displaying real time graphs. Save and print each real time graph after each trial. See Technical Hints to see how to save and print graphs.
Starting at the computer, stand still for 10 seconds, walk quickly away from the computer for one meter, stand still for 10 seconds, and walk slowly away from the computer.
Starting half way down the track, stand still for 10 seconds, walk quickly away from the computer for one meter, stand still for 10 seconds, and walk slowly away from the computer.
