A block of mass 1kg is pushed on a movable wedge of mass 2kg and height h=30cm with a velocity u=6m//sec . Before striking the wedge it travels 2m on a rough horizontal portion. Velocity is just sufficient for the block to reach the top of the wedge. Assuming all surfaces are smooth except the given horizontal part and collision of block and wedge is jerkless, the friction coefficition of the rough horizontal part is :

All surfaces are smooth. The acceleration of mass m relative to the wedge is
