A student tries to raise a chain consisting of three, Ask an Expert

Academics

A student tries to raise a chain consisting of three identical links. Each link has a mass of 210 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, and upward force of 13 N is applied to the chain by the string. Use Newton's laws to answer the following questions.

a) Find the acceleration of the chain

b) Find the force exerted by the top link on the middle link
