Correct answer
13
Step-by-step explanation
Let the ball fall a distance from the initial height.
Initial velocity
Acceleration m/s
Given that the magnitude of velocity is equal to the magnitude of acceleration due to gravity, we have m/s.
Using the equation of motion :
m
The distance fallen by the ball is m.
The height above the ground is
m
Answer:
Initial velocity
