  1. Question 1

    Q1. A car moves around a circular track of radius 50 m at a speed of 20 m/s. What is its centripetal acceleration?

    • A) 4 m/s²
    • B) 8 m/s²
    • C) 10 m/s²
    • D) 12 m/s²

    Answer: 8 m/s²

    Explanation: Centripetal acceleration = v² / r = (20)² / 50 = 400 / 50 = 8 m/s².
