Q)Two blocks A & B of masses m &2m respectively are connected together by a light spring of stiffness k & then placed on a smooth horizontal surface. The blocks are pushed towards each other such that spring gets compressed by a length 
& then released from rest . Find the work done on the block A by the spring , by the time the spring acquires its natural length is :
