a) what is the linear impulse exerted on the rod by the bullet as it passes through? (THE ANS IS: 4 * 10^4 dynes*s)

b) what is the angular velocity of the rod at the instant after the bullet emerges? (THE ANS IS: 3 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.
