Textbook Question
Chapter 5, Problem 2EP
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?

- In Peter Jackson's adaptation of The Two Towers, the wizard Gandalf falls from the Bridge of Khazad-dûm for a total screen time of 71 seconds. Darren wanted to calculate the maximum height the fall could have been and running the numbers concluded that it could be at most 4.94 km from the bridge to the heart of the mountain below. Is Darren's conclusion a fair estimation of the total fall distance?Be sure to:*State your claim with disagreeing with 4.94 km being a reasonable height for the fall.*Gather evidence from your choice of a combination of your own calculations and observations from the film (lord of the rings -Gandalf vs Balrog entire battle HD) *Connect your evidence to your claim by reasoning why it supports your claim. Any evidence you share should be directly linked with your reasoning to why or why not 4.94 km or 4,940 m is a reasonable estimate for the falling distance.
