Flick various numbers of marbles at each other at the same speed. Is there a way to predict the number of marbles that end up traveling in each direction? Is there a way to predict the speeds they will be traveling? For example, if you had 12 marbles traveling to the right and 7 marbles traveling to the left (all with the same mass and the same speed) and they collided, what would be the result?
