Solve the problem.
-A ball is thrown downward from a window in a tall building. Its position at time $t$ in seconds is $s=16 t^{2}+32 t$, where $s$ is in feet. How long (to the nearest tenth) will it take the ball to fall 119 feet?
A) $2.7 \mathrm{sec}$
B) $3.6 \mathrm{sec}$
C) $1.7 \mathrm{sec}$
D) $1.9 \mathrm{sec}$

To find the time it takes for the ball to fall 119 feet, set $s = 119$ and solve the equation $16t^2 + 32t = 119$. Rearranging gives $16t^2 + 32t - 119 = 0$. Solving this quadratic equation using the quadratic formula $t = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$ with $a = 16$, $b = 32$, and $c = -119$, we find $t \approx 1.9$ seconds.
