A block of mass m = 2.00 kg is attached to a spring of force constant k = 500 N/m as shown in the Figure below. The block is pulled to a position xi = 5.00 cm to the right of equilibrium and released from rest. Find the speed the block has as it passes through equilibrium if the horizontal surface is frictionless.
