When two objects are placed end-to-end, they are said to be in series. here, you will look at a block hanging from two springs in series, originally connected by an intermediate block which will then be removed. the first spring hangs from a hook in the ceiling and has a stiffness of 231 kg/s2. before a 222 g block is placed on the spring's bottom end, it has a length 18 cm. the second spring has a stiffness of 172.5 kg/s2 and equilibrium length 11 cm is attached at the bottom of the first block. a second block, which as a mass 296 g, is suspended from the bottom of the second block. (a) how far below the hook is first block? (b) how far below the hook is the second block? (c) what is the center of mass of the system? for the remaining questions, let the mass of higher block go to 0 g. (d) how far down below the hook is the connection point between the springs (where the higher block would have been)? (e) how far below the hook is the remaining block? consider the pair of springs as if they were a single spring. (f) what would its equilibrium length be? (a) what is the extension of the spring? (h) what would its spring constant be?
