A car is moving on a circular track with a radius of 200 m. If the maximum speed is 20 m/s, what is the minimum coefficient of friction required?
Q1. A car is moving on a circular track with a radius of 200 m. If the maximum speed is 20 m/s, what is the minimum coefficient of friction required?
Answer: 0.2
Explanation: The minimum coefficient of friction is given by μ = v² / (r * g) = 400 / (200 * 10) = 0.2.
