Question

a ball thrown upwards, reaching its highest point (max height) speeding up constant speed slowing down not accelerating

Explanation:

When a ball is thrown upwards, gravity acts downward, opposing its upward motion. As it moves toward max height, its upward velocity decreases over time, meaning it slows down. At the exact highest point, its instantaneous velocity is 0, but it is still accelerating due to gravity, so it is not moving at constant speed or not accelerating.

Answer:

slowing down
