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