A bullet of mass 10g and speed 500 m/s is fiered into a door and gets embeded exactly at the centre of the door. The door is 1 m wide and it weigh 12kg. It is hinged at one end and rotates about a vertical axis practially without friction. Calculate the angular speed of the door just after the bullet embeds into it?
