A particle of mass m is projected from the ground with an initial speed u0 at an angle α with the horizontal.
At the highest point of its trajectory, it makes a completely inelastic collision with another identical
particle, which was thrown vertically upward from the ground with the same initial speed u0. The angle that
the composite system makes with the horizontal immediately after the collision is
  • a)
    π/4
  • b)
  • c)
  • d)
    π/2
Correct answer is option 'A'. Can you explain this answer?
