  1. Question 1

    Q1. A wheel rotates with an angular acceleration of 3 rad/s². If its initial angular velocity is 2 rad/s, what will be its angular velocity after 2 s?

    • A) 6 rad/s
    • B) 8 rad/s
    • C) 10 rad/s
    • D) 12 rad/s

    Answer: 8 rad/s

    Explanation: Angular velocity (ω) = ω₀ + αt = 2 + 3 * 2 = 8 rad/s, using the formula ω = ω₀ + αt.
