(a) Melissa accidentally drops a pair of sunglasses from the top of a roller coaster, 64 feet above the ground. Simplify 64 16 to determine the number of seconds it takes for the sunglasses to reach the ground. (b) Suppose the sunglasses in the previous example were dropped from a height of 144 feet. Simplify 144 166 to determine the number of seconds it takes for the sunglasses to reach the ground.
