t = 3 seconds

Step-by-step explanation:

Given that,

Height of the building, h = 144 feet

Initial speed of the object, u = 0

To find,

After how many seconds does the object hit the ground.

Solution,

The equation of an object when it falls from height h is given by :

h(t)=-16t^2+ut+h

When the object hits the ground, h(t) = 0

-16t^2+144=0

16t^2=144

t = 3 seconds

So, the object will take 3 seconds to hits the ground.
