To solve the question, we need to analyze the relationship between angular velocity and angular acceleration for a rigid body that is free to rotate about an axis. ### Step-by-Step Solution: 1. **Understanding Angular Velocity and Angular Acceleration**: - Angular velocity (ω) is the rate of change of angular displacement and indicates how fast an object is rotating. - Angular acceleration (α) is the rate of change of angular velocity and indicates how quickly the angular velocity is changing. ...
