The upward velocity of the water in the stream of a particular fountain is given by the formula v = 32t + 28, where t is the number of secondds 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?

bobpursley,
If v=0
0=32t+28
solve for t.
