Task: Translation / Unit
User instruction:
Please translate the following problem into Korean using the International System of Units.

There are a blue ball and a red ball with equal masses. The blue ball has a momentum of 2 lb·ft/s and the red ball has a momentum of 5 lb·ft/s. The two balls are moving toward each other, approaching at a rate of 1.5 ft/s, and then collide. If the coefficient of restitution is 1, and friction and air resistance are neglected, what is the momentum of each ball after the collision?
