Question

1. enter your answer. use the description and the graph to answer the question. how can you interpret intervals c, d, and e?

Explanation:

• For interval C: The speed - time graph has a negative slope here, which means the speed is decreasing as time increases. So, this represents a deceleration (or negative acceleration) phase, where the object is slowing down.
• For interval D: The speed is zero (since the graph is on the time - axis) during this interval. This means the object is at rest (not moving) for the duration of interval D.
• For interval E: The speed - time graph has a positive slope here, which means the speed is increasing as time increases. So, this represents an acceleration (positive acceleration) phase, where the object is speeding up.

Answer:

• Interval C: The object is decelerating (slowing down).
• Interval D: The object is at rest (not moving).
• Interval E: The object is accelerating (speeding up).
