  1. Question 1

    Q1. A car is traveling at 20 m/s. If it decelerates uniformly to 10 m/s in 2 seconds, what is its deceleration?

    • A) 5 m/s^2
    • B) 10 m/s^2
    • C) 20 m/s^2
    • D) 25 m/s^2

    Answer: 10 m/s^2

    Explanation: Deceleration is calculated as negative change in velocity divided by time taken, which equals -10 m/s / 2 s.
