Solve.
-A ball is thrown downward with an initial velocity of 35 meters per second from a cliff that is 50 meters high. The height of the ball is given by the quadratic equation $h = - 4.9 t ^ { 2 } - 35 t + 50$ where $\mathrm { h }$ is in meters and $\mathrm { t }$ is the time in seconds since the ball was thrown. Find the time it takes the ball to hit the ground. Round your answer to the nearest tenth of a second.
A) $2.2 \mathrm { sec }$
B) $1.2 \mathrm { sec }$
C) $1.3 \mathrm { sec }$
D) $1.1 \mathrm { sec }$
