  1. Question 1

    Q1. A car is moving on a circular track with a radius of 250 m. If the maximum speed is 25 m/s, what is the minimum coefficient of friction required?

    • A) 0.25
    • B) 0.30
    • C) 0.35
    • D) 0.40

    Answer: 0.25

    Explanation: The minimum coefficient of friction is given by μ = v² / (r * g) = 625 / (250 * 10) = 0.25.
