Consider the following scenario: In a railroad yard, a train is being assembled. An empty boxczi, coasting at 3 m/s, strikes a loaded car that is stationary, and the car couple together. Each of the boxcars has a mass of 9,000 kg when empty, and the loaded car contains 55,000 kg of lumber. Assuming momentum is conserved, what is the total momentum of the system before and after the collision?
