Magnitudes of force

In the figure, a chain consisting of five links, each of mass 0.100 kg, is lifted vertically with constant acceleration of magnitude a =2.50 m/s2. Find the magnitudes of (a)the force on link 1 from link 2, (b) the force on link 2 from link 3, (c) the force on link 3 from link 4, and (d) the force on link 4 from link 5. Then find the magnitudes of (e)the force F on the top link from the person lifting the chain and (f) the net force accelerating each link.
