Question 702392
If Jack tosses a game cartridge to Darnell with an initial velocity of 35 feet per second, an equation for the height h feet of the cartridge after t seconds is h=-16t^2+35t+5. 
a. If the window is 25 feet above the ground, will Darnell have 0, 1, or 2 chances to catch the video game?
Solve: -16t^2+35t+5 = 25
----
-16t^2 + 35t - 20 = 0
b^2 -4ac = 35^2 - 4(-17)(-20) = -135
---
So there are no Real Number solutions.
Darnell will have 0 chances to catch the ball.
------------------------------------------------------
b. If Darnell is unable to catch the video game, when will it hit the ground?
Solve -16t^2 + 35t + 5 = 0
t = 2.322 seconds
