-A Ball Is Thrown Downward with an Initial Velocity $h = - 4.9 t ^ { 2 } - 35 t + 50$

question 41

Multiple Choice

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) \(1.1 \mathrm { sec }\)
