Homework Help: Block and wedge system all details

  1. Sep 28, 2011 #1
    1. The problem statement, all variables and given/known data
    okay this isnt really a question, but i didnt knew where to post it, tell me if it has to be posted somewhere else. a pic of the diagram would help a lot.
    A block is kept on the top of a wedge of angle alpha, can u explain what all happens, keeping all surfaces frictionless, what are their velocities and acceleration.

    2. Relevant equations
    I dont know

    3. The attempt at a solution
    i only know that a mgsin(alpha) will act on the block, nothing else..

    Draw a diagram.
    Put in the forces acting on the block.
    Resolve forces in components along the direction of motion and perpendicular to this direction.

    but i want to know how will the wedge be affected as the surface is frictionless...

    Draw a diagram and put in all the forces. It is good to make a contribution yourself first in line with the spirit of this forum.
