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?

Many equations have been developed by previous researchers. One of the established equation
worldwide is the E (energy) =m (mass) c* (speed of light) a simple equation that triumph of the
power and simplicity of fundamental physics. However, is the equation true? Use the method of
repeating variables to generate a dimensionless relationship between these parameters, showing
all of your work.
