  1. Question 1

    Q1. A car is moving in a circular path with a radius of 50 m. If the coefficient of friction is 0.8, find the maximum speed.

    • A) 15 m/s
    • B) 20 m/s
    • C) 25 m/s
    • D) 30 m/s

    Answer: 20 m/s

    Explanation: The maximum speed is given by v = √(μ * r * g) = √(0.8 * 50 * 10) = √400 = 20 m/s.
