SIMPLE HARMONIC MOTION Much HW- Consider the four block and-springis) systrim shows at right. Each block moves on a horizontal, frictionless uble. The blocks all have the same mass in, and all of the springs are identical and ideal, with spring comm . At the instant shown, each block is released from frid a distance A to the right off its equilibrium position (indicated by the dashed line), In case B. assume that each spring is at its equilibrium length when the black is at its equilibrium position. a. Rank the cases according to magnitude of the nel force on the block of the Instant shown, from largest to smallest. (Him: In case C, how far was the point connecting the two springs displaced when the block was displaced a distance A?) Explain. Can C b. Use your answers above to rank the cases according to the time it takes the block to return to its equilibrium position Explain. CPearce CaMom ?" Ed. for I CO, Boulder Shaffer, and the PHO, U. Wash
