Question 1018970
You throw a ball straight up from a rooftop 122 feet high with an initial velocity of 96 feet per second. During which time period will the ball's height exceed that of the rooftop?
-------------
h(t) = -16t^2 + 96t + 122
Find t for h(t) = 122
---
-16t^2 + 96t + 122 = 122
-16t^2 + 96t = 0
t = 0, t = 6
--> 0 < t < 6
