A student suspends a chain consisting of three links, each of mass m = 0.210 kg, from a light rope as shown in (Figure 1). The rope is attached to the top link of the chain, which does not swing. She pulls upward on the rope, so that the rope applies an upward force of 9.50 N to the chain. (I) Draw a free-body diagram for the entire chain, considered as an object, and one for each of the three links. (II) Use the diagrams of part (I) and Newton's laws to find (i) the acceleration of the chain, (a) the force exerted by the top link on the middle link, and (b) the force exerted by the middle link on the bottom link. Treat the rope as massless. (III)There are four objects of interest in this problem: the chain as a whole and the three individual links. For each of these four objects, identify the external forces acting on them. Besides the force of gravity, you should include only forces exerted by other objects that touch the object in question. Throughout this problem, assume the…
