I need to know the seconds

t = 3 seconds

Step-by-step explanation:

Here h(t) = -16t^2 + 144.  

When the quarter hits the ground, its height will be 0 feet.  Letting h(t) = 0 results in     -16t^2 + 144 = 0, or 16t^2 = 144, or

          144

t^2 = = 36/4 = 9 seconds^2

             16

Therefore, the time, t, required for the quarter to hit the ground is t = √9, or t = 3 seconds
