-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 1600 feet high.
A) $100 \mathrm { sec }$
B) $9 \mathrm { sec }$
C) $11 \mathrm { sec }$
D) $10 \mathrm { sec }$

To find the time it would take for an object to fall 1600 feet, set $s(t) = 1600$ and solve for $t$: $1600 = 16t^2$. Dividing both sides by 16 gives $t^2 = 100$, and taking the square root of both sides gives $t = 10$ seconds.
