Derivation
Head-on Elastic Collision and its 4 Special Cases

Derivation of the velocity formula for the elastic head-on collision of two different masses using conservation of momentum and conservation of energy.
Table of contents
Velocity of the first body after the collision
Velocity of the second body after the collision
Special case #1: Both collision partners have the same mass
Special case #2: One of the bodies is at rest before the collision
Special case #3: Collision of a heavy body with a light body at rest
Special case #4: Collision of a light body with a heavy body at rest
