SUMMARY
When a ball is thrown vertically upward, it reaches a maximum height where both speed and velocity become zero, while acceleration remains constant at 9.8 m/s² due to gravitational force. The discussion clarifies that acceleration is the reason for the reduction in speed and velocity as the ball ascends. Thus, at the peak of its trajectory, the ball experiences zero speed and velocity, but continuous acceleration directed downward.
