To determine the acceleration of the car based on the graph you mentioned, we need to analyze the relationship between speed (velocity) and time.
-
Calculate the slope: Acceleration is defined as the change in velocity divided by the change in time (a = Δv/Δt). The slope of the speed versus time graph gives us the acceleration.
-
Identify changes:
- If the speed increases uniformly (a straight line with a positive slope), then the acceleration is constant and can be calculated.
- If the line is horizontal (constant speed), the acceleration is zero.
- If the line is horizontal at the speed of zero, the car is at rest and there is no acceleration.
Without the specific values or further clarity from the graph, I can't provide a numeric answer. However, based on the options you provided:
- If the graph shows a straight line that rises, the acceleration is likely the slope of that line (check the change in speed over the change in time).
- If it shows a flat line, choose b. 0 m/s².
You would need to calculate or visualize the slope from the graph to select the right answer.
