Thats just a fn or kinetic energy and mass. So I'm still not sure. Is the answer obvious that it couldn't possibly increase the velocity of ball 3 or ?

This may be intuitively obvious to you and I'm just missing it. Say you had 3 balls each with a mass of 1g. Each moving at velocity of 10m/s on a 2D Cartesian plane. Ball 1 & 2 are moving toward the origin from opposite sides, so they are approaching each other at 20m/s. Ball 3 moving from...
