Solve the following problem involving a quadratic equation. Round to the nearest tenth if necessary.A ball is thrown downward with an initial velocity of 14 meters per second from a cliff that is
high. The height of the ball is given by the quadratic equation
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
from the ground.
A. After about 3.2 seconds, the ball will be from the ground.
B. After about 3.1 seconds, the ball will be from the ground.
C. After about 3.0 seconds, the ball will be from the ground.
D. After about 4.1 seconds, the ball will be from the ground.
