2. From the preceding calculation, it should be obvious that to experimentally time the distance of fall for a dropped object is critical. To gain an appreciation of how the distance
of fall varies with time, consider the daring experimenter shown in GL Fig. 5.1. Jo-Jo
will illustrate the time-distance relationship of free fall by stepping off a high, vertical cliff
with a timer in one hand and a marker in the other. For each second of fall, he makes a
mark on the cliff face.
But wait. Jo-Jo wants you to determine how far he would fall during each second for
the first 5 seconds. He requests you plot the results on a distance versus time graph for a
visual display
Oh, one other thing. He wants to open his parachute when reaching 60 mi/h. At what
time, or between which seconds, should he do this?
