  1. Question 1

    Q1. A car is moving on a circular track of radius 100 m with a speed of 20 m/s. What is its centripetal acceleration?

    • A) 2 m/s²
    • B) 4 m/s²
    • C) 6 m/s²
    • D) 8 m/s²

    Answer: 4 m/s²

    Explanation: Centripetal acceleration (a) = v² / r = (20)² / 100 = 4 m/s², using the formula a = v² / r.
