What happens when a lighter ball hits a stationary heavier ball??

Question

Assuming that it is pure energy transfer, meaning no energy lost to friction, sound energy, heat energy or others. Will the lighter ball rebounce or not? After you have answered, pls check:

==>If you say that it will rebounce, then Newton said that when object A acts a force on object B, object B acts an equal and opposite force on object A. So shouldn't this force and the force the lighter object originally had balance out one another (just like when the two balls are of the same mass).

==>If you say it will not rebounce, then why is it that when you drop a ball on the Earth, it will bounce back to its original height assuming no energy lost when bouncing? Shouldn't it just bounce the amount the Earth moved (which is insignificant to the human eye)?

Note: There is NO energy lost to other forms. Just pretend the balls are in total vacuum and the ground and balls are frictionless. Anyway I just want the general result, not the result in details. And when a baby hit the wall, the wall WILL move slightly.

Answer 1

Ideally should move as per F=MA equation. But since we cannot accurately calculate the energy loss, given normal circumstances anything could happen including the balls being stationary.

Answer 2

what is the mass and velocity of the lighter ball? and what is the mass of the heavier stationary ball?? need all these info.
I seen a baby knocking himself onto the wall. he fell and cry. the wall did not move though

Answer 3

they'll hit the gound on a similar time. In severe college we did this test dropping a heavy and a mild ball from the right of the stadium and that they hit the floor on a similar time

Answer 4

Bouncing is a function of elasticity. You have eliminated that, so I have no idea.
