Expert Answer:

First use the conservation of linear momentum.

This will give the velocity of the door after it is hit by the bullet.

Since the door is not free to move in a linear path it will rotate and the angular speed can be found from v = rω.

10/1000kg x 50m/s + 12kg x 0 = (12.010)(v)

Then use ω = v/r and find the angular speed of the door.
