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?
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?
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.
