Vfinal= [m1v1(initial)+ m2v2(initial)]/M1+M2
Vfinal= 20/2+2
hence Vfinal equals 5 m/s
Vfinal= 20/2+2
hence Vfinal equals 5 m/s

Answer -
The 2 kg mass must be still moving as the floor is frictionless.
Frictionless also means there's no air.
No air, no atmosphere.
No atmosphere, no life.
What a sad place that is.
A lonely 2 kg mass roaming around endlessly and aimlessly till the end of the world.
Let us all pray for the poor soul of the hopeless 2 kg mass.
May the poor soul find peace of mind and live a happy hopeless aimless endless eventless lifeless life.
