8. Decrease Ax by 10 cm while keeping the center in the same place (i.e., moving both photogates toward each other by 5 cm). Repeat steps 5 - 7. Continue decreasing Ax by 10 cm and repeating steps 5-7. Do this until you have six different values for Ax. Make sure that you start the cart from the same starting point at the top of the ramp each time. Analysis 1. For each of your six trials, calculate Vavg, the average velocity of the glide. Show your formula and show at least one example worked out. 2. Plot of a graph of Vavg vs. tavg (with tavg on the x-axis). For this graph, do the following: • Complete this graph by hand on graph paper, and be sure to label your axes. • Make sure you start the x-axis at tavg=0. Your y-axis does not need to start at 0. 3. On your graph, draw an estimated best-fit line. (This is a line that "best fits" your data. It does not have to actually pass through any of the data points.) 4. Which of the six average velocities that you calculated gives the closest approximation to the instantaneous velocity of the glider through the midpoint? Explain why! (Hint: consider the definition of instantaneous velocity - which of your six points best fits that definition?) 5. What value of tag on your graph would indicate a true instantaneous velocity? O 6. Using your graph, extrapolate from your collected data to determine the instantaneous velocity of the glider through the midpoint. Explain how you determined this value. (Hint: consider your answer to the previous question!) 7. Summarize your work, noting any unexpected results.
