Wedge and block initial momentum

Click For Summary
The discussion revolves around a physics problem involving a block sliding down a smooth triangular wedge on a frictionless floor. Participants analyze the conservation of linear momentum and energy to determine the velocities of both the block and the wedge when the block reaches the bottom. Initial conditions are clarified, emphasizing that the system starts at rest with the block at a height h before being released. There is confusion about the forces acting on the block and wedge during their interaction, particularly after the block leaves the wedge. The conversation highlights the importance of understanding initial conditions and the application of conservation laws in this context.

h=1/2 MV^2(M+m)÷m^2 g.
g is in multiplication with m^2.
Then write it as h=1/2 MV^2(M+m)/(m^2 g)

Well, your teacher had to be more clear.
