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 x subscript 0
& 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 :
left parenthesis A right parenthesis 1 half k x subscript 0 squared space space space space space space space space space space space space space space space space space space space space space space space space space space space space space left parenthesis B right parenthesis 1 fourth k x subscript 0 squared
