A particle of mass m is projected from the ground with an initial speed u0 at an angle  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

anonymous · Answer

What is the angle that it makes with the composite system

anonymous · Answer

The speed of the first particle at the highest point = u0cosÎ±
