Two blocks connected by a cord passing over a small, frictionless pulley rest on frictionless planes (fig. P5. 90). (a) which way will the system move when the blocks are released from rest? (b) what is the acceleration of the blocks? (c) what is the tension in the cord?.

With any turning vehicle, the rear wheels follow a shorter path than the front wheels. the longer the vehicle is, the greater the difference will be. truck drivers initially swing out before making a turn. what isn't shown in this illustration is as car straightens out, the front wheels must travel a greater distance and the tail end drags on the shortest path.
