Thank you so much, Madam.
method no 1 se answer nhi aa Raha hai sir
then when returning back velocity of B wrt ground is max and at this instant velocity of A wrt ground is zero

mera bhi yahi doubt hai V a/g = 0 ayega na
sir 1st method mein agar first block ki velocity negative consider ki ans match nahi ho raha
work done (neg) of 1/2 kx 2 kaise aya

spring after elongation tries to comes to its original position so it acts opposite to elongation
Sir part 1 wale question Mei final kinetic energy wrt center of mass equal to zero as sabki velocity COM ke barabar hai.....yeh point sirf samaj Mei nahi aa raha hai Sir...

KE ke sys wrt com formula mai velocity relative lete hai,which is zero as at final position v1=v2

v1 and v2 ki direction same hoti h ya nhi in case of final condition in case 1
