Thank you for your reply. I am just wonderning now: Is there any difference between the kinetic energies just before the separation (1) in the case of simple inclined plane without curved edge (unlike the question above, there is no velocity conservation by collision with the ground) and (2) in...

You mean that magnitude of vB' is differ from magnitude of vB? And you mean that the velocity of slope is encreased because of the potential energy (mgh)? That means, the velocity of slope is faster, compair to the case, if the velocity of block is not conserved?

This condision is given by the question. "The velocity of the block is conserved when it reaches at the ground." That means, the magnitude of vB' (the velocity just before the seperation) is same with vB (the velocity after saperation).

I have a problem in mechanics. On the wedge and block only the gravisational force (mg) is exerted (and there is no friction in this system). What is asked in the question is the final velocities of the wedge and the block (vB, vK). The velocity of the block is conserved when it reaches at the...
