Homework Statement
A student tries to raise a chain consisting of three identical links. Each link has a mass of 200 g. The three-piece chian is connected to a string and then suspended vertically, witht the student holding the upper end of the string and pulling upward. Because of the student's pull, an upward force of 14 N is applied to the chain by the string. Use Newton's laws to answer the following questions.
Find the acceleration of the chain
Find the force exerted by the top link on the middle link
Homework Equations
F = ma;
The Attempt at a Solution
So for the first answer, I used the F=ma equation. Force is 14 N and mass 200 g of one link. But when I divide those two, I get .07 which is not the answer. I know I am doing something wrong. I even tried converting the grams in kilograms which is .02 kg and when I divide the force of 14N by .02 kg, I get 70 which is not the answer. If you can help, I would appreciate it. Thank you.
