Initially speed is zero, then increases after some time it becomes constant. Acceleration (slope of v/t curve) of ball first decreases and after some time it becomes zero.

Initially speed is zero, then increases & after some time it becomes constant.
Acceleration (slope of $v / t$ curve) of ball first decreases and after some time it becomes zero.
