I agree with Carlos.

Work Step by Step

I agree with Carlos. The impulse that the bullet exerts on the block is equal in magnitude to the bullet's change in momentum. If the bullet bounces backward, the change in momentum is greater than if the bullet is embedded in the block. Therefore, the bullet exerts a greater impulse on the steel block. Since the impulse exerted on the steel block is greater, the steel block will have a greater momentum than the wood block. Since both blocks have the same mass, the steel block will be moving faster than the wood block.
