Question

A 500.0 g bird is flying
horizontally at 2.25 m/s, not
paying much attention, when it suddenly
flies into a stationary vertical
bar, hitting it 25.0 cm below the top
(Fig. ). The bar is uniform,
0.750 m long, has a mass of 1.50 kg,
and is hinged at its base. The collision
stuns the bird so that it just
drops to the ground afterward (but
soon recovers to fly happily away).
What is the angular velocity of the bar (a) just after it is hit by the bird
and (b) just as it reaches the ground?

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.
