  1. Question 1

    Q1. A particle is moving in a circular path with a radius of 2 m. If the centripetal acceleration is 8 m/s², what is its speed?

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

    Answer: 4 m/s

    Explanation: v² = a * r = 8 * 2 = 16, v = √16 = 4 m/s, using a = v²/r.
