Question 136113: please i need urgent help here. pleaseeeeeeeeeeee
The height of an object propelled upward from a height of 128 feet at an initial velocity of 112 feet per second is given by the equation h = -16t2 + 112t + 128. After how many seconds does the object hit the ground?

Answer by vleith(2983) (Show Source): You can put this solution on YOUR website!
Given:
When does it hit the ground? Means, when does h = 0

t = 8, -1
Since t cann hit the ground a second before you throw it, the only reasonable answer is 8 seconds.
Check your answer by using 8 for t and finding h
