if the ques is that sleeping man one then the ans is
even the slightest disturbance will wake the man up so
2mv2/2=2mgh
v of b is sqrt(2gh)
Now using V1=((m1-m2)u1+2m2u2)/(m1+m2)
U1=0 and VI we have found out as sqrt(2gh)
So u2 comes out to be sqrt(9gh/2)
Using work ene theorem
For A
Mgh=m(u2)2/2-mv2/2
Substituting the value of u2
V comes out to be sqrt(2.5gh)
