A string with one end fixed on a rigid wall, passing over a fixed frictionless pulley at a distance of 2 m from the wall, has a point mass 
of 2 kg attached to it at a distance of 1 m from the wall. A mass 
of 0.5 kg is attached to the free end. The system is initially held at rest so that the string is horizontal between wall and pulley and vertical beyond the pulley as shown in Fig. The system is released from the rest from the position as shown

(a)
When
strikes the wall, vertically downward component of its displacement from initial position is 1 m and its distance from pulley 
is
While its initial distance from the pulley was 
It means vertically upward displacement of mass 
is

Let 
strike the wall with velocity 
Since the string between the two blocks always remains taut, therefore at any instant speed of 
is equal to that component of velocity of 
which is along the string 
. Hence, velocity of 
when 
strikes the wall is 
where
According to law of conservation of energy, loss of potential energy of
