The ball speeds up as it travels to the ground as gravity pulls it down to make it go fast.

About 30 mph.
It decreases.
it slows down
It goes faster
That means, of course, that the velocity (and the speed) doesn't change.
It increases.
it travels at c (speed of light in a vacuum)
A woman throws a baseball from the front of an airplane to the back. From the perspective of the woman, the baseball travels at an average speed of 15 m/s. To an observer on the ground, the airplane is traveling at a constant speed of 820 km/h. What is the speed of the baseball from the perspective of the ground observer?
The maximum speed that a vessel will achieve relative to ground is its own maximum speed through water plus the speed of the the moving water downstream.
the same thing that happens when you divide by zero.
Light speed slows down in the glass.
