SUMMARY
The average angular acceleration of a fan's blades transitioning from medium speed to high speed is calculated using the formula \( \alpha = \frac{\Delta \omega}{\Delta t} \). With the initial angular velocity at −225 rad/s and the final angular velocity at −355 rad/s, and a time interval of 3.05 seconds, the correct calculation yields an average angular acceleration of 42.6 rad/s². The sign of the angular acceleration should be noted as negative, indicating a clockwise rotation.
