Question 712844: A ball is thrown into the air vertically with a velocity of 112 feet per second. The ball was released 6 feet above the ground. The height above the ground t seconds after release is modeled by h(t)=-16t^2+112t+6. 1.)When will the ball reach 130 feet? 2.)Will the ball reach 250 feet? 3.)In how many seconds after its release will the ball hit the ground?

h(t)=-16t^2+112t+6. 1.)When will the ball reach 130 feet?
h(t) = -16t^2 + 112t + 6
-16t^2 + 112t + 6 = 130
Solve for t
(There will be 2 solutions, 130 ft going up, 130 ft coming back down)
---------------
2.)Will the ball reach 250 feet?
-16t^2 + 112t + 6 = 250
Same as #1
---------------------
3.)In how many seconds after its release will the ball hit the ground?
-16t^2 + 112t + 6 = 0
Ignore the negative solution
