Two blocks of unequal masses are tied by a spring. The blocks are pulled stretching the spring slightly and the system is released on a frictionless horizontal platform. Are the forces due to the spring on the two blocks equal and opposite. If yes, is it can example of Newton's third law?

Two blocks of equal mass m are connected by an unstretched spring and the system is kept at rest on a frictionless horizontal surface. A constant force F is applied on the first block pulling away from the other as shown in Fig. If the extension of the spring is x_(0) at time t , then the displacement of the first block at this instant is

A spring block system is placed on a rough horizontal floor. The block is pulled towards right to give spring some elongation and released.

Two blocks of mass m_(1) and m_(2) , resting on a frictionless table, are connected by a stretched spring and then released -

Two blocks of masses m_(1) and m_(2) are connected by a massless spring and placed on smooth surface. The spring initially stretched and released. Then :
