-The distance, $s ( t )$, in feet traveled by a freely falling object is given by the function $s ( t ) = 16 t ^ { 2 }$, where $t$ is time in seconds. Use this formula to find the time it would take for an object to fall to the ground from a cliff that is 144 feet high.
A) 9 seconds
B) 4 seconds
C) 2 seconds
D) 3 seconds

To find the time it takes for an object to fall 144 feet, we set $s(t) = 144$ and solve for $t$: $144 = 16t^2$. Dividing both sides by 16 gives $t^2 = 9$, and taking the square root of both sides gives $t = 3$ seconds.
