  1. Question 1

    Q1. A car is moving on a circular track with a radius of 50 m. If the coefficient of friction is 0.4, what is the maximum speed?

    • A) 10 m/s
    • B) 14 m/s
    • C) 18 m/s
    • D) 20 m/s

    Answer: 14 m/s

    Explanation: Maximum speed = √(μ * g * r) = √(0.4 * 10 * 50) = √200 = 14.14 m/s, using v = √(μgr).
