Question 724183: you and your friend are walking around a tennis court that has a 10-foot high fence around it. You see two tennis balls lying outside the fence. You pick up a ball and try to throw it with an initial velocity of 22 feet per second. Did the ball made it over the fence? Answer by Alan3354(69443) (Show Source):

------------
h(t) = -16t^2 + 22t, height in feet, t in seconds
----
The max ht is the vertex
t at the vertex = -b/2a = -22/-32 = 11/16 seconds
---
h(11/16) = -16(121/256) + 22*(11/16) (max ht)
= 242/16 - 121/16 ft
= 7.5625 feet
Not high enough
