  1. Question 1

    Q1. A car is moving on a circular track. If the radius is 100 m and the coefficient of friction is 0.5, what is the maximum speed?

    • A) √(500) m/s
    • B) 10 m/s
    • C) 20 m/s
    • D) √(1000) m/s

    Answer: √(500) m/s

    Explanation: Maximum speed is given by √(μrg) = √(0.5 * 100 * 10) = √500 m/s.
