A particle moves in a circular path of radius 3 m with an initial angular velocity of 2 rad/s and an angular acceleration of 1 rad/s². What is its angular velocity after 4 seconds?
Q1. A particle moves in a circular path of radius 3 m with an initial angular velocity of 2 rad/s and an angular acceleration of 1 rad/s². What is its angular velocity after 4 seconds?
Answer: 6 rad/s
Explanation: Angular velocity (ω) after time t is given by ω = ω0 + αt, where ω0 is initial angular velocity and α is angular acceleration. So, ω = 2 + 1*4 = 6 rad/s.
