Problem on block sliding on a wedge
Consider a block of mass 'm' kept on the hypotenuse of a right triangular wedge of mass 'M'. Calculate the accelaration of the wedge and the block.
Hence find the force that should be applied to 'M' so that 'm' does not move?

is there no friction?
in this case the interaction force between the block and the wedge is the normal vincular reaction, that is equal to the normal compnent of the block weight that is:
where alpha is the lower angle of the wedge. So the horizontal force between the wedge and the block is
Considering the wedge it receives a force equal to F so it moves with an acceleration equal to

For the second question I donīt understand if m must not move respect a fix coordinate or respect to the wedge...
