Ideal for quick review sessions before physics midterms or graduate-level qualifiers.
Let ( X ) = horizontal position of the wedge (positive to the right). Let ( x ) = horizontal position of the block relative to the wedge, measured down the slope. The block’s absolute horizontal coordinate: [ X_\textblock = X + x \cos\alpha ] Vertical coordinate of the block (taking table as ( y=0 )): [ Y_\textblock = -x \sin\alpha ] (the minus sign because block moves downward as ( x ) increases).
