Dear nitin,


Your answer is correct


Vg = - (mb/mg)* Vb


    = - ((10* 10^(-3))/5) * 400


    = - (4/5)


    = - 0.8 m/s

it is correct, 


according to law of conservation of momentum,


m1v1=m2v2


v2 = m1v1/m2


v2 = (10x10-3)(400)/5


v2 = (0.01x400)/5


v2 = 4/5 = 0.8 ms-1

your ans is corect


 from conservation of momentam


  M1.V1 + mv2 =0


              V1=-mv2/M


                  =-4/5=-0.8m/s
