Question

In a one-dimensional collision between two particles, their relative velocity is Vector v₁ before the collision and Vector v₂ after the collision.

(a) Vector v₁ = Vector v₂ if the collision is elastic.

(b) Vector v₁ = Vector v₂ if the collision is elastic.

(c) |Vector v₁| = |Vector v₂| in all cases.

(d) Vector v₁ = - k Vector v₂ in all cases, where k ≥ 1.

Answer 1

Correct Answer is: (b, c, & d)
