  1. Question 1

    Q1. A cyclist is moving on a circular track with a radius of 30 m. If his centripetal acceleration is 3 m/s², what is his speed?

    • A) 9 m/s
    • B) 10 m/s
    • C) 12 m/s
    • D) 15 m/s

    Answer: 9 m/s

    Explanation: Speed (v) = √(a_c * r) = √(3 * 30) = 9.48 ≈ 9 m/s, using the formula a_c = v² / r.
