A bullet of mass 10 g and speed 500 `m.s^(-1)` is fired into a door and it gets embedded exactly at the centre of the door. The door is 1.0 m wide and of mass 12 kg. It is hinged at one end and it rotates about a vertical axis practically without friction. Find the angular speed of the door just after the bullet gets embedded into it.

Text Solution
