The correct option is:
interval AB → constant speed
interval BC → decreasing speed
interval CD → constant speed
interval DE → increasing speed
The correct option is:
interval AB → no motion
interval BC → constant speed
interval CD → no motion
interval DE → acceleration
To determine the correct option, let's analyze the graph and the motion of the object for each interval:
- interval AB: The graph shows that the object's distance traveled remains constant. Therefore, the motion during this interval is no motion.
- interval BC: The graph shows a straight line with a positive slope, indicating that the object is moving at a constant speed. Therefore, the motion during this interval is constant speed.
- interval CD: The graph once again shows that the object's distance traveled remains constant. Therefore, the motion during this interval is no motion.
- interval DE: The graph shows a curved line, indicating that the object's speed is changing. This is an example of acceleration. Therefore, the motion during this interval is acceleration.
Based on this analysis, the correct option is: interval AB → no motion, interval BC → constant speed, interval CD → no motion, interval DE → acceleration.
