SUMMARY
A disk starting from rest rotates about its central axis with a constant angular acceleration, covering an angular displacement of 25 radians in 5.0 seconds. The average angular acceleration, denoted as α, is calculated using the formula α = Δω / Δt. The average angular velocity, ω_avg, can be derived from the total angular displacement and time. These calculations are essential for understanding rotational dynamics in physics.
