Consider two objects/particles: Object 1 has mass 3m and speed v and Object 1 has mass
2m and speed 2v, respectively. In each of the three different scenarios, the objects collide
inelastically and stick together after the collision.
Scenario A: The objects move toward each other and collide head-on.
Scenario B: Object 2m chases Object 3m and collides with from behind.
Scenario C: The objects move at right angles before the collision.
