Two blocks A and B of masses m and 2m respectively, attached at opposite ends of a spring of constant K, placed on a smooth horizontal surface. Spring is initially at its natural length l. A is given a velocity 2V_(0) and B given velocity V_(0) as shown. Maximum separation between m and centre of mass of the system will be :

Answer»
