A student tries to raise a chain consisting of three identical links. Each link has a mass of 370 g. The three-piece chain is connected to a string and then suspended vertically, with the student holding the upper end of the string and pulling upward. Because of the student's pull, an upward force of 14.0 N is applied to the chain by the string. Use Newton's laws to answer the following questions.
Find the acceleration of the chain.
(Take the free fall acceleration to be g = 9.80 m/s^2)
Find the force exerted by the top link on the middle link.
