Quizplus · Accepted Answer

The distance an object falls is given by the formula:
distance = (1/2) * acceleration * time^2
For this question, the acceleration is the acceleration due to gravity, which is 9.8 m/s^2 downward. Plugging in time = 1 second, we get:
distance = (1/2) * 9.8 m/s^2 * (1 s)^2 = 4.9 m
Therefore, the ball will have fallen 4.9 meters after 1 second.
