The correct answer is 0.00 kg·m/s. This is because momentum is conserved in a closed system, meaning that the total momentum before the collision is equal to the total momentum after the collision. Since the two objects have the same mass and velocity but are moving directly towards each other, their momenta cancel each other out and the total momentum after the collision is zero.
