SUMMARY
The discussion centers on calculating the time it takes for an object to fall from a height of 70 yards, given two data points: a fall from 20 yards takes 6 seconds and a fall from 100 yards takes 9 seconds. The relevant equation for this problem is h = h₀ - v₀t - (1/2)at², where h is the final height, h₀ is the initial height, v₀ is the initial velocity, t is time, and a is acceleration due to gravity. By applying this equation and the provided data, one can derive the time for the 70-yard fall using the known acceleration and initial conditions.
