E's-'2 . Use the printed graphs obtained in Step P4 to answer Parts (a) through (d) below. (a) Circle all regions of relatively constant displacement on the composite graph. With an arrow and the word "high", label the points where the glider is the highest off the ground. What is the value of the velocity at these points? What should it be? (b) On the position graph, label the points where the glider bounces { draw an arrow at those points and write the word "bounce" ]. Explain in a few words what happens to the velocity ' s magnitude and direction when a bounce occurs. Explain how your data shows this behavior. (c) On the acceleration chart, circle the regions where the glider is striking the air-track bumper. In what direction {up or down along the track) is the force of the glider on the airtrack bumper oriented? What direction [up or down) is the acceleration that you have just circled? Does this seem correct? If you are having trouble with the signs of the acceleration, remember that the acceleration is constant most of the time and is directed downwards due to gravity. (d) Imagine that you throw a ball up in the air, assuming the release position of your hand as zero elevation more or less, and plot its position for the total ight. Looking at your data plots from Step P4, does any region correspond to the plot of your ball toss? Consider shifting regions, inverting regions, adding constants, subtracting constants, et ceteracould you make your data look like that of a ball toss? If so, explain how you would do this
