<PRE><B>Question 631778</B>
Amir pitched a baseball at an initial height of 5.9 feet with a velocity of 73.16 feet per second. About 
how long will it take the ball Amir pitched to hit the ground?
---
Height is zero when the ball hits the ground.
Solve: -16t^2+73.16t + 5.9 = 0
----
t = [-73.16 +- sqrt(73.16^2 - 4*-16*5.9]/(2*-16)
---
t = 4.65 seconds
------------------
