  1. Question 1

    Q1. A wheel is rotating with an initial angular velocity of 2 rad/s and an angular acceleration of 1 rad/s². What is its angular velocity after 3 s?

    • A) 5 rad/s
    • B) 4 rad/s
    • C) 3 rad/s
    • D) 6 rad/s

    Answer: 5 rad/s

    Explanation: Angular velocity (ω) after time t is given by ω = ω0 + αt. So, ω = 2 + 1*3 = 5 rad/s.
