2. A system is composed of ball 1 of mass m1 and ball 2 of mass m2. Each ball is traveling at speed v, but in the opposite direction from the other ball. The total momentum of the system is m1v in the direction of ball 2. Which equation describes the relationship between m1 and m2?
m2 = m12
m2 = 0.5m1
m2 = 2m1
m2 =9m1

3. A system consists of three billiard balls. Each ball has mass m and is traveling at speed v. One ball is traveling north, another ball is traveling east, and the third ball is traveling south. What is the momentum of the system?

mv, heading west
mv, heading east
Square Root 2 mv, heading east
3mv, heading east
