  1. Question 1

    Q1. A car is moving on a circular track with a radius of 150 m. If the coefficient of friction is 0.3, what is the maximum speed?

    • A) 18 m/s
    • B) 20 m/s
    • C) 22 m/s
    • D) 25 m/s

    Answer: 20 m/s

    Explanation: The maximum speed is given by v = √(μ * g * r) = √(0.3 * 10 * 150) = √450 = 21.21 m/s, closest to 20 m/s (approx.).
