Two blocks of masses 2 kg and 1 kg are connected by a light inextensible string passing over a light frictionless pulley. Initially, both blocks are held at the same horizontal level and then released from rest. Taking g = 10 m·s⁻², what distance does the centre of mass of the two-block system move during the first 2 s?
