Taking a Galilean transformation to the lab frame, before the collision we get:

p1= m1 v1 = m1(v∗1 + V) = p∗ + m1 V

p2= m2 v2 = m2(v∗2 + V) = −p∗ + m2 V

while after the collision we get:

q1= q∗ + m1 V (7.21)

q2= −q∗ + m2 V. (7.22)

Exploiting the fact that p2= 0 we find

p1= p∗(1 + m1/m2) (7.23)

q1= q∗ + p∗m1/m2 (7.24)

q2= p∗ − q∗. (7.25)
