Answer:
Explanation:
The amount of movement is the product of the mass of a body because of its speed, the speed is that of the center of mass; The equation is:
  p = mv
Where v is the velocity of the center of mass of the body, what we have to do is clear the velocity
   V = p / m
 It is our case for each body and as the amount of movement is a vector we must write it for each axis
  V1x = p1x / m1
  V2x = p2x / m2
