Multiple Choice

Solve.
-A ball is thrown upward with an initial velocity of 35 meters per second from a cliff that is 70 meters high. The height of the ball is given by the quadratic equation $h = - 4.9 t ^ { 2 } + 35 t + 100$ where $h$ is in meters and $t$ is the time in seconds since the ball was thrown. Find the time that the ball will be 30 meters from the ground. Round your answer to the nearest tenth of a second.

A) $9.4$ seconds
B) $9.3$ seconds
C) $8.8$ seconds
D) $8.9$ seconds
