Answer:

3 Seconds

Step-by-step explanation:

To find how long it will take the object to hit the ground, set the equation equal to 0

0=144-16t² *add 16t² to both sides*

16t²=144 *divide both sides by 16*

t²=9 *take the square root of both sides*

t=3

It will take three seconds for the object to hit.
