Why Does Second Collision in Ballistic Pendulum Lead to Initial State?

[QUOTE="The Head, post: 6463491, member: 321011"] Thanks for your reply and that does make sense. Though if they aren't equal, I get a similar equation with two solutions (one equal to zero and one non-zero), but in that case the velocities wouldn't have a clean exchange. The simplest version of non-equal masses would be if the first ball were lighter than the second ball, and after the initial collision the first ball would swing back to some degree and the second would swing forward to some degree. Then they'd collide again and it would force the first ball back to it's initial position and the second would come to rest. How does one know to choose the non-zero velocity for collision #1, but not #2? [/QUOTE]
