Answer:
The answer is

Step-by-step explanation:

multiply both sides by 2 to get

divide both sides by n to get

subtract L from both sides to get the answer

When the object reaches the ground, the height is zero, so:
0 = 144 - 16t^2
then you just solve for t, so subtract the 144 over
-144 = -16t^2
then divide by the -16
9 = t^2
then take the square root of both sides
3 = t
therefore, it will take three seconds for the object to reach the ground.
