Two 491 g blocks of wood are 1.63 m apart on a frictionless table. A 10.67 g bullet is fired at 415 m/s toward the blocks. It passes all the way through the first block, then embeds itself in the second block. The speed of the first block immediately afterward is 5.05 m/s. What is the speed of the second block after the bullet stops in it?
