Engineering Mechanics
If u₁ and u₂ are the velocities of two moving bodies in the same direction before impact and v₁ and v₂ are their velocities after impact, then coefficient of restitution is given by

(u₂ + u₁)/(v₂ + v₁)

(v₁ - v₂)/(u₁ - u₂)

(v₂ - v₁)/(u₁ - u₂)

(u₁ - u₂)/(v₁ - v₂)

(u₂ + u₁)/(v₂ + v₁)

(v₁ - v₂)/(u₁ - u₂)
