A bullet of mass 10 g and speed 500 m/s ...

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 weighs 12 kg. It is hinged 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.

A

`0.25 rad"/"s`

B

`0.625 rad"/"s`

C

`0.125 rad"/"s`

D

`0.65 rad"/"s`
