At a resort, tourists watch swimmers dive from a cliff to the water 144 feet below.
A diver's height h above the water t seconds after diving is given by
h = −16t2 + 144.
How long does a dive last?
height of the water is 0
-16t%5E2+%2B+144+=+0
-16t%5E2+=+-144+
t%5E2+=+%28-144%29%2F%28-16%29
t%5E2+=+%2B9
t = sqrt%289%29
t = 3 seconds
