In an inelastic collision of a moving billiard ball with a second ball at rest, I understand that the two balls have the same velocity after contact, correct?
But at the instant of contact how do the velocites of the two balls change instantaneously? Doesn’t that imply an infinite force?
What am I missing here? Thanks.
