Two masses m₁ and m₂, with m₁= 3 m₂, undergo a head-on elastic collision. If the particles were approaching with speed v before the collision, with what speed are they moving apart after collision? A) v B) v/3 C) 3v/4 D) 3v

Question

Quizplus · Accepted Answer

In an elastic collision, the relative speed of separation is equal to the relative speed of approach. Since they were approaching each other with speed v, they will move apart with speed v after the collision.

Two Masses M1 and M2, with M1 = 3 M2
