  2. as frictional force is uN but as block B will move further and block A will remain at its place the value normal force will decrease leading to decrease in friction as contact between block A and B will continously decreasebecause part of A will move out from contact with B

  4. Respected sir Is the relation between v v1 and v2 obtained from conservation of linear momentum? If so can momentum really be conserved for there is an external force of friction acting on the ball-block system (before) and after collision. Please help.

    Ans 1 ->
    Just before and just after the collision its conserved
