Homework Statement
A chain consisting of five links, each of mass 0.090 kg, is lifted vertically with a constant acceleration of a = 3.6 m/s2. Find the magnitude of the force that link 3 exerts on link 2.
Note: The chains are connected vertically
Homework Equations

The Attempt at a Solution
How would I calculate the force? I've tried the force of gravity minus the force of 3 chain links but that didn't work. Numerically I did: I called down the positive direction.
[tex] (3 * .09kg)(9.8 m/s^2) - (3 * .09kg)(3.6 m/s^2) [/tex]
