Neglecting air resistance, the upward velocity of the water in the stream of a particular fountain is given by the formula \(v=-32 t+28\), where \(t\) is the number of seconds after the water leaves the fountain. While going upward, the water slows down until, at the top of the stream, the water has a velocity of 0 feet per second. How long does it take a droplet of water to reach the maximum height?
