  1. Question 1

    Q1. A cyclist is moving on a circular track with a radius of 20 m. If his speed is 10 m/s, find the minimum coefficient of friction required.

    • A) 0.25
    • B) 0.5
    • C) 0.75
    • D) 1

    Answer: 0.5

    Explanation: Minimum coefficient of friction = v² / (r * g) = (10)² / (20 * 10) = 0.5, using μ = v² / (r * g) formula.
