question 210

Multiple Choice

Solve.
-A ball is thrown downward with an initial velocity of 28 meters per second from a cliff that is 60 meters high. The height of the ball is given by the quadratic equation $h = - 4.9 t ^ { 2 } - 28 t + 120$ where $\mathrm { h }$ is in meters and $\mathrm { t }$ is the time in seconds since the ball was thrown. Find the time that the ball will be 60 meters from the ground. Round your answer to the nearest tenth of a second.

• A) \(2.7 \mathrm { sec }\)
• B) \(1.7 \mathrm { sec }\)
• C) \(1.8 \mathrm { sec }\)
• D) \(1.6 \mathrm { sec }\)
