Which describes the ball and motion between 20 m and 80 m on the graph?

Without the specific graph to reference, I can provide a general interpretation. If the ball's motion between 20 m and 80 m is represented by a straight line, it indicates uniform motion at a constant speed. If the line is curved, it suggests that the ball is accelerating or decelerating. Additionally, if the line slopes downward, the ball may be returning towards the starting point, while an upward slope indicates it is moving away.
