If an object is dropped from a height of 144 feet, the function h(t)=-16t^2 +144 gives the height of the object after t seconds.
Vaselesa [24]
If the object hit the ground, then this mean that the height is 0, right?
so solve for it like this: 

0= -16t^2+144
-144 = -16t^2
Divide by (-16)
9= t^2 
square root both sides
t= 3 or -3
there is no negative time then the object will hit the ground after 3 secs
