A long block B rests on a smooth horizontal plane. A small block A of mass half that of B is placed at one end of B and given a horizontal velocity u. If mu is the co-efficient of friction between the two blocks, then the time elapsed before the two blocks attain a common velocity is ( 2u)/( n mug) wher n is
