  1. Question 1

    Q1. A particle is moving in a circular path of radius 4 m with an initial angular velocity of 3 rad/s and an angular acceleration of 2 rad/s². What is its angular velocity after 2 seconds?

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

    Answer: 7 rad/s

    Explanation: Angular velocity (ω) after time t is given by ω = ω0 + αt. So, ω = 3 + 2*2 = 7 rad/s.
