Question 269465: If an object is propelled upward from ground level with an initial velocity of 224 feet per second, its height h in feet t seconds later is given by the equation h = 224t - 16t^2. After how many seconds does the object hit the ground?
You can put this solution on YOUR website! Set the function = 0 and solve. The ground is height = 0.
We get
(i)
divide by -16 to get
(ii)
add 14 to get
(iii)
take a square root to get
(iv)
It is will take sqrt(14) or about 3.74 seconds to hit the ground
