A particle is dropped from a certain height onto a fixed surface
at which it collides inelastically. Which of the following represents
true phase-space (momentum-position) graph? Taking upward direction as
positive and x=0 at the surface
Show answer and solution
Initial velocity is zero and x=+H
Just before collision velocity hence momentum is negative and position
is zero. Just after collision, particle will change its direction. So,
option (C) is correct.
