  1. Question 1

    Q1. A wheel starts from rest and rotates with a constant angular acceleration of 2 rad/s². What will be its angular velocity after 3 s?

    • A) 4 rad/s
    • B) 5 rad/s
    • C) 6 rad/s
    • D) 7 rad/s

    Answer: 6 rad/s

    Explanation: Angular velocity (ω) = ω₀ + αt = 0 + 2 * 3 = 6 rad/s, using the formula ω = ω₀ + αt.
