which graph represents a car with negative acceleration?

Explanation:

Step1: Recall acceleration - speed relation

Acceleration is the rate of change of speed. Negative acceleration means speed is decreasing over time.

Step2: Analyze each graph

• In graph A, speed decreases as time increases.
• In graph B, speed increases with time (positive acceleration).
• In graph C, speed is constant (acceleration = 0).
• In graph D, speed increases linearly with time (positive acceleration).

Answer:

A.
