  1. Question 1

    Q1. A car is moving on a circular track. If the coefficient of friction is 0.8, what is the maximum velocity for a radius of 25 m?

    • A) 10√2 m/s
    • B) 14 m/s
    • C) 16 m/s
    • D) 20 m/s

    Answer: 10√2 m/s

    Explanation: v = √(μ * g * r) = √(0.8 * 10 * 25) = √200 = 10√2 m/s.
