The total momentum is 
Explanation:
The diagram illustration this system is shown on the first uploaded image (From physics animation)
From the question we are told that
The mass of the first object is 
The speed of the first mass is 
The mass of the second object is 
The speed of the second object is assumed to be 
The total momentum of the system is the combined momentum of both object which is mathematically represented as

substituting values


A model train traveling at a constant speed around a circular track has a constant velocity. FALSE.
