Explosions in One Dimension: Jacques and George Meet in the Middle

question 22

Multiple Choice

Explosions in one dimension: Jacques and George meet in the middle of a lake while paddling in their canoes. They come to a complete stop and talk for a while. When they are ready to leave, Jacques pushes George's canoe with a force to separate the two canoes. If we can neglect any resistance due to the water, what is correct to say about the final momentum and kinetic energy of the system consisting of the two canoes and the two men inside?

• A) The final momentum is in the direction of but the final kinetic energy is zero.
• B) The final momentum is in the direction opposite of but the final kinetic energy is zero.
• C) The final momentum is in the direction of and the final kinetic energy is positive.
• D) The final momentum is zero and the final kinetic energy is zero.
• E) The final momentum is zero but the final kinetic energy is positive.
