The correct option is:
interval AB → constant speed
interval BC → decreasing speed
interval CD → constant speed
interval DE → acceleration
The correct answer is:
interval AB → constant speed
interval BC → decreasing speed
interval CD → constant speed
interval DE → increasing speed
To determine the motion of the object for each time interval, you need to analyze the slope of the distance-time graph.
- For interval AB, the slope is constant, indicating constant speed.
- For interval BC, the slope is negative (decreasing), indicating decreasing speed.
- For interval CD, the slope is zero, indicating no change in distance over time and thus constant speed.
- For interval DE, the slope is positive (increasing), indicating increasing speed.
Therefore, the option "interval AB → constant speed, interval BC → decreasing speed, interval CD → constant speed, interval DE → increasing speed" is correct.
