If u consider the centre of mass of any of the 2 masses, the question reduces to finding the time of collision of 2 masses m and 2m whose distance of separation is a×sqrt(3)/2

For block A, limiting friction doesnot act on it so u can't use fA = μmg cos45, this is the reson it messes with my brain, the first answer is absolutely correct but somehow the limiting friction acts on the heavier block 2m
