A particle is moving in a circular path with a constant angular acceleration. What is the angular displacement in the first 2 seconds if the initial angular velocity is 0?
Q1. A particle is moving in a circular path with a constant angular acceleration. What is the angular displacement in the first 2 seconds if the initial angular velocity is 0?
Answer: 2α
Explanation: θ = ω₀t + 0.5αt² = 0 + 0.5α(2)² = 2α.
