  1. Question 1

    Q1. A wheel rotates with a constant angular acceleration of 2 rad/s². If its initial angular velocity is 1 rad/s, what is its angular velocity after 3 s?

    • A) 5 rad/s
    • B) 6 rad/s
    • C) 7 rad/s
    • D) 8 rad/s

    Answer: 7 rad/s

    Explanation: ω = ω0 + α*t = 1 + 2*3 = 7 rad/s, using the formula for angular velocity under constant angular acceleration.
