f is propotional to the     -change in momentum/time
force proportional to -mu-mv/t=m(v-u)/t =ma
force propotional to-ma= f=kma.    (k=1) 
therefor F=ma

Initial momentum of B= m2u2
Total initial momentum (A+B)= m1u1+m2u2

Final momentum of A= m1v1

According to Newton's 3rd law 
Action= - reaction
m1v1-m2u2/t = -(m2v2-m2u2/t)
m1v1- m1u1= -m2v2+m2u2
