A horizontal spring attached to a wall has a force constantof k 5 850 N/m. A block of mass m 5 1.00 kgis attached to the spring and rests on a frictionless,horizontal surface as in Figure P8.59. (a) The blockis pulled to a position xi 5 6.00 cm from equilibriumand released. Find the elastic potential energy storedin the spring when the block is 6.00 cm from equilibriumand when the block passes through equilibrium.(b) Find the speed of the block as it passes through theequilibrium point. (c) What is the speed of the blockwhen it is at a position xi/2 5 3.00 cm? (d) Why isntthe answer to part (c) half the answer to part (b)?
