**Velocity vs. Time Graph Analysis for Zero Acceleration Intervals**

This velocity vs. time graph depicts the changes in velocity of an object over time, helping us identify intervals where acceleration is zero. The graph is segmented into various labeled sections (A through H), each representing different patterns of motion.

**Graph Explanation:**

- **Vertical Axis (Velocity, m/s):** Represents the velocity of the object in meters per second, ranging from -4 m/s to 4 m/s.
- **Horizontal Axis (Time, s):** Represents time in seconds, ranging from 0 to 16 seconds.

**Plot Analysis:**
- **Intervals A and F:** The graph is a horizontal line, indicating constant velocity, hence zero acceleration. 
- **Intervals B, D, E, G, and H:** The graph has a slope, indicating changing velocity, hence some acceleration.
- **Interval C:** Another horizontal segment showing constant velocity, resulting in zero acceleration.

**Question:**

*Use the velocity vs. time graph below to determine all intervals in which acceleration is zero.*

- ○ A. C, F
- ○ B. B, D, E
- ○ C. F
- ○ D. A, E, G
- ○ E. none of the above

In conclusion, intervals A, C, and F have zero acceleration due to their constant velocity, making option A correct.

The image displays a velocity vs. time graph used to identify intervals where the velocity is negative.

**Graph Explanation:**
- The y-axis represents velocity in meters per second (m/s).
- The x-axis represents time in seconds (s).

**Graph Details:**
- Segment A: From 0 to 2 seconds, the velocity is negative, decreasing from 0 to -2 m/s.
- Segment B: From 2 to 4 seconds, the velocity is positive, increasing to 2 m/s.
- Segment C: From 4 to 6 seconds, the velocity remains constant at 4 m/s.
- Segment D: From 6 to 8 seconds, the velocity decreases to 0 m/s.
- Segment E: From 8 to 10 seconds, the velocity is negative at -2 m/s.
- Segment F: From 10 to 12 seconds, the velocity further decreases to -4 m/s.
- Segment G: From 12 to 14 seconds, the velocity increases to 0 m/s.
- Segment H: From 14 to 16 seconds, the velocity is positive, increasing to 2 m/s.

**Question and Options:**
Determine all intervals in which velocity is negative.
- A. D, E
- B. E, F, G
- C. A, E, F, G
- D. C, F
- E. None of the above

**Correct Answer:**
C. A, E, F, G

The velocity is negative during Segments A (0 to 2 seconds), E (8 to 10 seconds), F (10 to 12 seconds), and G (12 to 14 seconds).
