  1. Question 1

    Q1. A cyclist is moving on a circular track with a radius of 50 m. If his speed is 25 m/s, find the minimum coefficient of friction required.

    • A) 0.5
    • B) 1.25
    • C) 1.5
    • D) 2

    Answer: 1.25

    Explanation: Minimum coefficient of friction = v² / (r * g) = (25)² / (50 * 10) = 1.25, using μ = v² / (r * g) formula.
