SUMMARY
The correct velocity-time graph for a ball thrown straight up is represented by option D. This graph accurately depicts the ball's velocity reaching zero at the apex before falling back down, illustrating the effects of gravity throughout the motion. The discussion highlights the importance of understanding acceleration as a vector, emphasizing that while the ball decelerates on the way up, it accelerates on the way down, confirming that the acceleration due to gravity is consistently negative. Participants debated the merits of options C and D, ultimately concluding that only D correctly represents the ball's motion under the influence of gravity.
