Question 888939: Help.after experimentation two pacific institute physics students find that when a bottle of California wine is shaken several times, held upright, and uncorked,its cork travels according to the function defined by s(t)=-16t^2 + 64t+3, what is its height in feet above the ground t seconds after being released. After how many seconds will it reach its maximum height? What is the maximum height?

0=-16t^2 + 64t+3
0=-32t+64
32t=64
t=2 seconds
y=-16t^2 + 64t+3
y=-64+128+3
y=67 feet in 2 seconds
