the total potential energy of a system of multiple springs is defined to be the sum of the potential energies stored in each of the springs. The blacks all have the same mass nctonles the instant shown, each block is ele leoxk on a horizontal, rhecks n dea th spring constant k. At Case A the four block- m, and all of the released from rest a a ro the right of its equilibrium position nt indicated by the dashed line). me that each spring is at its equilibrium Case B a case B, assume length when the block is at its equilibrium tank the cases according to magnitude of the net Ran or on the block at the instant shown, from largest to smallest. (Hint: In case C, how far was the point was displaced a distance A?) Explain Case C Case D b Use your answers above to rank the cases according to the time it takes the block n reaun its equilibriam position
