Question

The graph represents velocity vs. time for Carla. A graph with horizontal axis time (seconds) and vertical axis velocity (meters per second). A line runs in straight segments from 0 seconds 15 meters per second to 1 seconds 13 meters per second to 2 seconds 10 meters per second to 3 seconds 4 meters per second to 4 seconds 0 meters per second to 6 seconds 4 meters per second. Which best describes the graph? Carla sped up in the beginning of her trip, stopped, and then slowed down. Carla had a greater acceleration in the beginning than in the end. Carla slowed down in the beginning of her trip, stopped, and then sped up. Carla had a continuous acceleration throughout the entire trip.

Answer 1

Answer 2

Answer:

The statement that best describes the graph is Carla slowed down in the beginning of her trip, stopped, and then sped up.

Explanation:

Data:

Horizontal axis = time.

Vertical axis = velocity (m/s).

A line runs in straight segments

• from 0 seconds 15 m/s.
• to 1 seconds 13 m/s.
• to 2 seconds 10 m/s.
• to 3 seconds 4 m/s.
• to 4 seconds 0 m/s.
• to 6 seconds 4 m/s.

According to the data present in the graph, it can be seen that Carla starts with a speed in her career, which decreases over time. After four seconds she stops, remains stopped for one second and starts running again, with an initial speed of 4 m/s.

In conclusion, the graph show Carla -who is moving- slows down until she stops, and then starts the race again.
