  1. Question 1

    Q1. A car is moving on a circular track of radius 200 m with a speed of 30 m/s. What is its centripetal acceleration?

    • A) 4 m/s²
    • B) 4.5 m/s²
    • C) 5 m/s²
    • D) 6 m/s²

    Answer: 4.5 m/s²

    Explanation: Centripetal acceleration (a) = v² / r = (30)² / 200 = 4.5 m/s², using the formula a = v² / r.
