Question

Two equal mass billiard balls collide elastically in 1-D.

A) What is their relative velocity if they are initially approaching each other with speeds vA and vB? NOTE: their initial relative velocity , vR, is given by vR = vA - vB

B) What are their final velocities if vB is initially zero?

C) What can you conclude about 1-D elastic collisions?

Explanation / Answer

relative velocities in Opposite directions is VR = VA+VB

VR = VA+VB

-------------------------

apply

m1u1 + m2u2 = m1v1 +m2v2

final Common velocity V = m1VA/(m1+m2)

----------------------------------
during this collision, momentum in Conserved
