  1. Question 1

    Q1. A car is moving on a circular track with a radius of 80 m. If its centripetal acceleration is 5 m/s², what is its speed?

    • A) 15 m/s
    • B) 20 m/s
    • C) 25 m/s
    • D) 30 m/s

    Answer: 20 m/s

    Explanation: Speed (v) = √(a_c * r) = √(5 * 80) = 20 m/s, using the formula a_c = v² / r.
