A small block of mass M moves on frictionless surface of an inclined plane, as shown in figure. The angle of the incline suddenly changes from $$60^\circ$$ to $$30^\circ$$ at point B.
The block is initially at rest at A. Assume that collisions between the block and the incline are totally inelastic (g = 10 m/s$$^2$$)
The speed of the block at point C, immediately before it leaves the second incline is
