In the system shown in figure, mass 
is released from rest from position ( 
). Suppose potential energy of 
at point 
with respect to point 
is 
. Dimensions of 
are negligible and all surfaces are smooth. When mass 
reaches at point ( 
)

Since there is no external force acting on system, Momentum is conserved.
Let velocity of mass 
is 
in left direction and velocity of mass 2 m is 
in right direction
Given 
wrt 
.
Height of 
wrt 
is 
So, 
Since there is no external force acting on system. Energy is conserved.
putting 
Kinetic energy of 
similarly, 
momentum
