1.	Two blocks of masses m and 2m rest on a frictionless horizontal surface. They are connected by an ideal spring of relaxed length l and stiffness constant k. By means of a massless thread connecting the blocks the spring is held compressed to a length l//2. the whole system is moving with speed v in a direction perpendicular to the length of the spring. the thread is then burnt. Answer the following questions in terms of l,km,v Before burning, the rato of kinetic energy to potential energy is:
