  1. Question 1

    Q1. A particle moves in a circular path with a radius of 4 m. If its centripetal acceleration is 9 m/s², what is its speed?

    • A) 6 m/s
    • B) 8 m/s
    • C) 5 m/s
    • D) 7 m/s

    Answer: 6 m/s

    Explanation: Speed (v) = √(ar) = √(9 * 4) = √36 = 6 m/s, using the formula a = v² / r.
