The time to hit the ground is 9 seconds
How to determine the time to hit the ground?
The equation of the function is given as:
h(t) = -16t^2 + Initial height
The initial height is
Initial height = 1296 feet
So, we have:
h(t) = -16t^2 + 1296
When the ball hits the ground, the value of h(t) is 0
So, we have:
-16t^2 + 1296 = 0
This gives
-16t^2 = -1296
Divide both sides by -16
t^2 = 81
Take the square root of both sides
t = 9
Hence, the time to hit the ground is 9 seconds
