  1. Question 1

    Q1. A stone is tied to a string and is whirled in a vertical circle of radius 1 m at a rate of 2 revolutions per second. What is its angular velocity?

    • A) 2π rad/s
    • B) 4π rad/s
    • C) 6π rad/s
    • D) 8π rad/s

    Answer: 4π rad/s

    Explanation: Angular velocity (ω) is given by 2πf = 2π * 2 = 4π rad/s.
