A small block of mass M moves on a frictionless surface of an inclined plane, as shown in figure. The angle of the incline suddenly changes from 60° to 30° at point B. The block is initially at least at A. Assume that collisions between the block and the incline are totally inelastic. (g = 10 m/s2)
If collision between the block and the incline is completely elastic, then the vertical (upward) component of the velocity of the block at point B, immediately after it strikes the second incline, is
    Correct answer is '0'. Can you explain this answer?

    A small block of mass M moves on a frictionless surface of an incline...
    In case of elastic collision, component of v1 parallel to BC will remain unchanged, while component perpendicular to BC will remain unchanged in magnitude but reverse in its direction.
    Now, the vertical component of velocity of the block is given by:
    Now the vertical component of velocity of the block is,
    v' = vT cos 30° - v2 cos 60°
    = 0
