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 |
