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