Answer
The correct answer is **Its vertical speed changes and its horizontal speed remains the same.**Here's why:* **Vertical Speed:** Gravity constantly acts on the ball, pulling it downwards. This causes the vertical speed to change continuously. Initially, the vertical speed is upwards, decreasing to zero at the highest point, and then increasing downwards as the ball falls.* **Horizontal Speed:** Neglecting air resistance, there are no horizontal forces acting on the ball once it's thrown. Therefore, the horizontal speed remains constant throughout the trajectory.
