A wedge with mass rests on a frictionless horizontal table top. A block with mass is placed on the wedge. There is no friction between the block and the wedge. The system is released from rest.

2. Relevant equations

(-gm)/((M+m)tan(alpha)+(M/tan(alpha)))

3. The attempt at a solution

The question is to calculate the vertical and horizontal components of the BLOCKS acceleration.

I know that the above equation is the acceleration of the wedge, so i know that the acceleration of the block should be equal an opposite. Is this actually true? I'm not too sure. Also, would I swap the tan functions for cosine and sine for horizontal and vertical acceleration respectively?

Could some one please point me in the right direction! :) that would be much appreciated!
