a 100-g bullet is fired horizontally into a 14.9kg block of wood resting on a horizontal surface and the bullet becomes embedded in the block. if the muzzle velocity of the bullet is 250 m/s , what is the speed of the bullet immedatly after the impact (neglect surface friction)

  • physics -

    Isn't momentum conserved? Isn't the final speed of the block and bullet the same?
