SOLUTION: Diving time. The time t (in seconds) that it takes for a
cliff diver to reach the water is determined by the height
h (in feet) from which he dives:
t= Square Root of h/16

: Diving time. The time t (in seconds) that it takes for a
cliff diver to reach the water is determined by the height
h (in feet) from which he dives:
t= Square Root of h/16
Sky diving. The formula in Exercise 109 accounts for the
effect of gravity only on a falling object. According to that
formula, how long would it take a sky diver to reach the
earth when jumping from 17,000 feet? (A sky diver can
actually get about twice as much falling time by spreading
out and using the air to slow the fall.)

--------------------
Using the formula you gave, t = sqrt(17000/16)
t = 32.596 seconds (neglecting air friction)

I don't know what Exercise 109 is, I don't have the book.
