The spinning top in the figure has a moment of inertia of 5×10^(-3) kgm^2 and its initial angular velocity is 320 rad/s. The spinning top rotates freely along the AA' axis. The rope wrapped around the neck of the top of the top is pulled in such a way that the 7.5 N tension force on it remains constant. If the rope does not slip when pulled from the neck of the top, what will be the angular velocity of the top when a total of 95 cm of rope is pulled from the neck of the top of the top? a) 1056.8 rad/s B) 324.4 rad/s NS) 642.5 rad/s D) 750.0 rad/s TO) 826.6 rad/s

Definition Definition Rate of change of angular displacement. Angular velocity indicates how fast an object is rotating. It is a vector quantity and has both magnitude and direction. The magnitude of angular velocity is represented by the length of the vector and the direction of angular velocity is represented by the right-hand thumb rule. It is generally represented by ω.
