A thick wood block of mass 2.2 kg stands at rest on a horizontal and frictionless table. Sally fires a bullet of mass 4.5 g. The bullet reaches a speed of 380 m/s and hits the block. After the collision the bullet is stuck inside the block. What is the speed of the center of mass of the bullet-block system before the collision in meters per second?  What is the speed of the wood block after the collision in meters per second?
