  1. Question 1

    Q1. A car is moving on a circular track of radius 50 m with a constant speed. If its centripetal acceleration is 2 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) = √(ar) = √(2 * 50) = √100 = 10 m/s, using the formula a = v² / r.
