1) airplanes are often used to drop water on forest fires in an effort to stop the spread of the fire.
the time t it takes the water to travel from height h to the ground can be derived from the equation h = 1/2 •
gt2 where g is the acceleration due to gravity (32 feet/second2).

2) suppose a plane drops water from a height of 1,024 feet. how many seconds will it take for the water to hit the ground?

a) 4
b) 16
c) 9
d) 8
