Refer the figure..

The smaller block has a mass of 5kg and the wedge a mass of 30kg.

The angle made by the wedge with the smooth horizontal floor is 30⁰.

The horizontal length of the wedge is 0.5m

Friction is negligible on all surfaces

 

Neglect the size of smaller block

 

Determine the distance the wedge moves when the smaller block moves to the bottom of the plane....
