The given velocity-time graph shows two different cars that accelerate on a long straight road
Correct answer: B. II only.
- A. I only.
- B. II only.
- C. I and III
- D. II and III
Explanation
The correct answer is II only. Car II's velocity-time graph demonstrates the acceleration pattern that meets the criteria described in the question. Car I and Car III do not show the correct acceleration characteristics: Car I might accelerate too slowly or decelerate, and Car III's graph might indicate a different acceleration behavior that is not aligned with the requirements. Therefore, only Car II fulfills the necessary conditions.

About Acceleration
Acceleration measures the rate at which velocity changes with time, including changes in speed, direction or both. Work includes average and instantaneous acceleration, the relation a = Δv/Δt, uniform acceleration equations, and interpreting velocity time and displacement time graphs, with acceleration carefully distinguished from velocity.
