  1. Question 1

    Q1. A cyclist is moving on a circular track. If the radius of the track is 40 m and the coefficient of friction is 0.2, what is the maximum speed?

    • A) 8 m/s
    • B) 10 m/s
    • C) 12 m/s
    • D) √(80) m/s

    Answer: √(80) m/s

    Explanation: Maximum speed is given by √(μrg) = √(0.2 * 40 * 10) = √80 m/s.
