question 200

Multiple Choice

Solve.
-A ball is thrown downward with an initial velocity of 28 meters per second from a cliff that is 110 meters high. The height of the ball is given by the quadratic equation $h = - 4.9 t ^ { 2 } - 28 t + 110$ where $h$ is in meters and $t$ 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) \(2.6\) seconds
• B) \(2.8\) seconds
• C) \(3.7\) seconds
• D) \(2.7\) seconds
