A  0.23 kg block on a horizontal frictionless surface is attached to a spring whose force constant is 470 N/m. The block is pulled from its equilibrium position at x = 0m to a displacement x = +0.080m and is released from rest. The block then executes simple harmonic motion along the x-axis (horizontal). When the displacement is x = 0.021 m, the kinetic energy of the block is closest to:
