Answer:
4v/3
Explanation:
Assume elastic collision by the law of momentum conservation:
where v is the original speed of car 1, v1 is the final speed of car 1 and v2 is final speed of car 2. m1 and m2 are masses of car 1 and car 2, respectively
Substitute 
Divide both side by 
, then multiply by 6 we have
So the final speed of the second car is 4/3 of the first car original speed
