In a ballistics test, a 24 g bullet traveling horizontally at 1200 m/s goes through a 31-cm-thick 320 kg stationary target and emerges with a speed of 910 m/s. The target is free to slide on a smooth horizontal surface. What is the targetâs speed just after the bullet emerges?

The  velocity is  

Explanation:

From the question we are told that

   The  mass of the bullet is  

    The initial speed of the bullet is  

   The mass of the target is  

    The  initial velocity of target is  

    The  final velocity of the bullet is  is  

Generally according to the law of momentum conservation we have that
