The two blocks shown in Figure are moving with an initial speed v. (a) If the system is frictionless, find the distance d the blocks travel before coming to rest. (Let u = 0 correspond to the initial position of block 2.) (b) Is the work done on block 2 by the rope positive, negative, or zero? Explain. (c) Calculate the work done on block 2 by the rope.
