Answer 1

To determine the acceleration of the car using a speed-time graph, look for the slope of the line. The acceleration is the change in speed divided by the change in time.

1. If the line is horizontal, the speed is constant, and the acceleration is 0 m/s².
2. If the line is diagonal (linear), the slope of the line can be calculated to find the acceleration.

Since I cannot see the graph you mentioned, I can’t calculate the acceleration directly. However, here is how you can determine it based on the options provided:

- **0 m/s²:** This indicates the car is not speeding up or slowing down (constant speed).
- **0.10 m/s², 1.0 m/s², or 10 m/s²:** These imply that the car is accelerating at a constant rate.

To find the correct value, measure the rise over run (change in speed over change in time) if the line is sloped. Choose the option that best matches that calculated slope.

Feel free to provide details from the graph, and I can assist you further!
