To solve the problem, we need to determine the acceleration of the car during the interval AB based on the velocity-time graph provided.

Step-by-Step Solution:

1. Understand the graph: The graph depicts velocity versus time. The slope of the line in this graph represents the acceleration, since: $\text{Acceleration} = \frac{\Delta v}{\Delta t}$ where:

   • $\Delta v$ is the change in velocity,
   • $\Delta t$ is the change in time.

2. Identify interval AB: On the graph, find points A and B. From what I can interpret:

   • At point A, the car is at rest (velocity = 0).
   • At
