Write a Newton's second law equation for each of the four objects. From these. what is the y component of the acceleration of the chain? Express your answer with the appropriate units. A student suspends a chain consisting of three links, each of mass m = 0.170 kg, from a View Available Hint(s) 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. (s) Draw a free-body diagram for the entire chain, considered as an HA object, and one for each of the three links. (b) Use the diagrams of part (a) and Newton's laws to find (i) the acceleration of the chain, (ii) the force exerted by the top link on the middle link, and (ii) the force exerted by the middle link on the bottom link.
