  1. Question 1

    Q1. A car moves in a circular path with a radius of 50 m. If the coefficient of friction is 0.4, find the maximum speed.

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

    Answer: 14 m/s

    Explanation: The maximum speed is given by v = √(μ * r * g) = √(0.4 * 50 * 10) = √200 = 14.14 m/s.
