Question 1034991: a ball is shot out of a homemade air cannon. it flies through the air such that its height as a function of time is given by
h=-16t^2+64t+10
where h is the height of the ball and t is the time since if was fired in seconds.
max estimates that it takes 4 seconds for the ball to hit the ground and cole estimates it takes 5 seconds. algebraically determine who is closer and support your answer.

Given that the height, h(t), is given by
h(t) = -16t^2 + 64t + 10
we need to find t when h = 0, so set it equal to zero and solve...
-16t^2 + 64t + 10 = 0
8t^2 - 32t - 5 = 0
Use the quadratic formula:
and we get
t = 4.15 seconds (or so)
Max is closer.
