A block of mass m = 2.00 kg is attached to a spring of force constant k = 5.00 x 102 N/m that lies on a horizontal frictionless surface as shown in Figure P13.8. The block is pulled to a position xi = 5.00 cm to the right of equilibrium and released from rest. Find (a) the work required to stretch the spring and (b) the speed the block has as it passes through equilibrium.
