h=-16t2+s
h = height in which it hits its target = 0 feet
s = initial height at which jump occurs = 64 feet
Farmer Brown had a silo that was 64 feet high. He joined a circus and started jumping from the top of his silo into the pond below. How many seconds did it take him to hit the water 64 feet below?
