1. On the lower right corner of the video you can see an image of a graph called the spectrum of the sound of the car horn. The
spectrum shows that the car horn is made up of dozens of sounds, each represented by a vertical line, called a peak, on the
spectrum
Take a close look at the spectrum. What is the longest wavelength where the car horn spectrum has a peak?
Hint: If you are having trouble reading the vertical axis, you can switch the video to full screen using the button on the lower right of

Be sure to distinguish between trial #l's data points and trial# 2's data points. On a second sheet of graph paper, plot speed (y-axis) vs. time (x-axis) for the motion of your lab groups cart for trial #1 and trial #2. (Both data sets on the same axis). Be sure to distinguish benveen trial #1 's data points and trial# 2's data points. From the plot of your graphs, The relationship between a sont describe the relationship between distance and time. land time 3b. From the plot of your graphs, the relationship between Speed describe the relationship between land time speed and time. 4a. What information can be obtained You can determine the speed from the slope of a distance vs. time graph? 4b. From the distance vs time graphs Trial #1 (show work) determine the speed of the cart in both trial #1 and trial #2. Trial #2 (show work) the start not 7. 5. Why is of measurement tape, from the first from the first few dots, not truy the The start of the measurment tope truly uniform motion? Uniform motion because it's 6. What information can be obtained Information that can be octaired Ota constant Speed from the area under a speed vs. is time graph? How can we tell from our plot of speed vs. time, if the speed was constant? 8. Describe some sources of error in your experiment. Be specific and explain. Do not list a source of error that you can control, or human error. 9. For the sources of error that you mentioned, suggest some ways in which these can be corrected. 2
