  1. Question 1

    Q1. A body is moving in a circular path with a radius of 5 m. If its centripetal acceleration is 20 m/s², what is its speed?

    • A) 5 m/s
    • B) 10 m/s
    • C) 15 m/s
    • D) 20 m/s

    Answer: 10 m/s

    Explanation: Speed (v) = √(a_c * r) = √(20 * 5) = 10 m/s, using the formula a_c = v² / r.
