Blocks A and B are connected by rope I and are pulled at constant speed across a rough surface by rope 2, which is attached to block B, as shown. Compare the magnitude of the tensions in ropes 1 and 2. 1? 0000 0 Nothing can be determined about how the two tensions will compare without knowing the acceleration of the system. .'he magnitude of the tensions in the two ropes will not be equal. r1 -he tension in the two ropes will be equal due to Newton's third law. The tension in the two ropes will be equal due to Newton's second law. I DON'T KNOWYET
