M1= 200gm or 0.2kg, v1= 0.3m/s m2=400gm or 0.4 kg v2=? m1v1=m2v2 because after collision two ball are stop so collision is elastic and it's not depends on mass(action reactions rule) and it's then possible when two ball moving in opposite direction 0.2×0.3=0.4×(-v2) 0.06/0.4=- v2 v2=-0.15 ans.

Let after collision the velocity of ball B is "V" as they both have come to rest after collision their momentum will be equal so M1V1= M2V2 then 0.2×0.3 = 0.4×V2....(converted mass into kg) then by solving we will get V2 which is velocity of ball b is 0.15sec
