Question 1121456: Standing on top of a house 48 feet above the ground, Matt shoots a trick basketball shot upward according to the equation h=-16t^2 + 32t + 48, where h is the height of the ball in feet and t is the time in seconds. How long will it take for Matt's airball to hit the ground? Answer by rothauserc(4718) (Show Source):
You can put this solution on YOUR website! h = -16t^2 + 32t + 48
:
we want the value of t when h = 0
:
-16t^2 +32t +48 = 0
:
divide both sides of = by -16
:
t^2 -2t -3 = 0
:
factor the left side of the =
:
(t-3) * (t+1) = 0
:
t = 3 or t = -1
:
we reject the negative value for t
:
*******************************************
t = 3
:
Matt's airball hits the ground in 3 seconds
