Answer:
D. Increases.
Explanation:
The kinetic energy of the ball is given by:
[tex]K=\frac{1}{2}mv^2[/tex]
where
m is the mass of the ball
v is the speed of the ball
We see that the kinetic energy is proportional to the square of the speed. As the ball continues to fall, its speed increases (because the ball has a constant acceleration, g=9.8 m/s^2, the acceleration due to gravity), so its kinetic energy also increases.
