A bullet of mass 10 g and speed 500 m/s is fired into a door and gets embedded exactly at the centre of the door. The door is 1.0 m wide and weight 12 kg. It is hinges at one end and rotates about a vertical axis practically without friction. Find the angular speed of the door just after the bullet embeds into it.
