Question

Use the exact values you enter in previous answer(s) to make later calculation(s).

The cliff-divers of Acapulco are famous for diving from steep cliffs that overlook the ocean into places where the water is very shallow.
(a) Suppose a cliff-diver jumps from a cliff that is 18 m above the water. What is the speed of the diver just before he enters the water? Ignore air drag. (Assume the diver drops straight down rather than leaping forward.)
m/s

(b) If the water is 5.9 m deep, what is the acceleration of the diver after he enters the water? Assume this acceleration is constant and it begins at the moment his hands enter the water. (Also assume the diver descends the full depth. Enter the magnitude of the acceleration.)
m/s2

Explanation / Answer

a)
18.78 m/s

----------------------------------

b)
V2 = 2*a*d >>>

a = V2 / 2*d

   = + 29.90 m/s2
