Question 313615: If a ball is thrown vertically upward from a height of 5 ft, with an initial velocity of 96 ft/s, its height h after t seconds is given by h = -16t^2 + 96t + 5. How long does it take the ball to pass through a height of 120 ft on the way back down to the ground?
You can put this solution on YOUR website! If a ball is thrown vertically upward from a height of 5 ft, with an initial velocity of 96 ft/s, its height h after t seconds is given by h = -16t^2 + 96t + 5. How long does it take the ball to pass through a height of 120 ft on the way back down to the ground?
----------------------
h = -16t^2 + 96t + 5
120 = -16t^2 + 96t + 5 solve for t
-16t^2 + 96t + 5 = 120
-16t^2 + 96t + -115 = 0
