Question

Please help someone!!!
A ball is thrown straight down from the top of a building at a velocity of 16 ft./s. The building is 480 feet tall, and the acceleration due to gravity is 32 ft./s2.

This problem can be represented using the following equation.
(1/2)32t2 + 16t = 480

How much time will it take the ball to reach the ground?
