A 0.15kg cart moving east and a 0.30kg cart moving west stick together after they collide on a horizontal, frictionless track. Immediately after the collision the combined mass is at rest. State what this observation tells you about the magnitudes of the initial momenta of the two carts and explain your answer in one sentence.
