Bullet and wood block

A bullet is fired horizontally into a wood block resting on a horizontal, frictionless surface. If the mass of the bullet is 0.02 Kg and the velocity is 600 m/s, what is the velocity of the wood block after the bullet is embedded in it? Assume the wood block has a mass of 50 kg. a. 1 m/s b. 2 m/s c. 2.5 m/s d. 0.24 m/s
