  1. Question 1

    Q1. A car is moving on a circular track with a radius of 50 m. If the maximum speed is 25 m/s, what is the coefficient of friction?

    • A) 0.5
    • B) 1.25
    • C) 1.0
    • D) 1.5

    Answer: 1.25

    Explanation: μ = v² / (r * g) = 25² / (50 * 10) = 1.25, using v = √(μgr).
