3.  A chain consists of identical links, each with a mass of 2.5 kg. You grab the top link and pull the chain so that it accelerates upwards at a constant rate of 2.5 m/s2.    a)  Draw a free body diagram of the bottom three links (labeled 1, 2, 3). Label all forces and use double subscript notation to denote which object exerts the force and which object is experiencing the force.   b)  Find the magnitude of the force exerted on link 1 by link 2, in Newtons.   c)  Find the magnitude of the force exerted on link 2 by link 3, in Newtons.
