    Maths urgent help

    If there is a cubic log with a mass "M" and edges which have a length "2a" and is kept on top of a table,and there is a hole dug inside it right in between two parraral faces of this cube. This hole starts from the middle of one top edge(A) and leads on to the bottom of the cube.The hole angles "beta" to the floor.If a mass of "m"(P) is kept on (A) and it travels along the hole and when (AP)=x prove that at that time the velocity of (P) is [(2M+m)gxsin(beta)]/(M+msin^2(beta)
