  1. Question 1

    Q1. A car moves on a circular track of radius 100 m. If it completes one lap in 62.8 s, what is its average speed?

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

    Answer: 10 m/s

    Explanation: Average speed = Total distance / Time = 2 * π * 100 / 62.8 = 10 m/s, using formula for circumference of a circle.
