  1. Question 1

    Q1. A car is moving at 30 m/s when it hits a wall and comes to rest in 0.5 seconds. What is the acceleration of the car?

    • A) a = Δv / Δt
    • B) a = v^2 / Δt
    • C) a = v / Δt
    • D) a = Δv^2 / Δt

    Answer: a = Δv / Δt

    Explanation: The correct formula is a = Δv / Δt, as acceleration is the change in velocity over time.
