A man of mass 85kg stands on one end of a uniform board of length 2m and mass 15kg. The other end is tied to the floor by a steel cable, and the board is supported from below just 0.5 m from the cable end (see figure).

A boy of mass 50kg is standing at one end of a boat of length 9m and mass 400kg . He runs to the other end. The distance through which the centre of mass of the boat boy system moves is
