Question

A student is exploring the relationship between velocity and acceleration. The graph below shows the acceleration of a drone.

Acceleration
Speed (m/s)

Time (s)


Which segments show no acceleration?
Responses
A Segment OA and segment EFSegment OA and segment EF
B Segment BC and segment FGSegment BC and segment FG
C Segment AB and segment EFSegment AB and segment EF
D Segment CD and segment DE

Answer 1

To determine which segments show no acceleration, we need to look for segments on the graph where the acceleration (the slope of the velocity vs. time graph) is equal to zero. Typically, on an acceleration versus time graph, a value of zero acceleration is represented by a horizontal line (a line parallel to the x-axis).

1. **Determine where acceleration is zero:** Identify segments on the graph where the value of acceleration is 0 (horizontal line).
2. **Assess each response:**
- **A**: If segments OA and EF are horizontal lines, they show no acceleration.
- **B**: If segments BC and FG are horizontal lines, they show no acceleration.
- **C**: If segments AB and EF are horizontal lines, they show no acceleration.
- **D**: If segments CD and DE are horizontal lines, they show no acceleration.

Since I don't have the actual graph, make a visual examination of each segment based on the above steps. Compare which segments are horizontal to conclude which segments represent no acceleration.

Based on standard knowledge:
- Choose the response that identifies all segments that are horizontal.

**Without the specific graph provided**, I can't definitively select a correct option. Please visually confirm the segments against the described criteria to pick the right answer.
