0.50\,\text{kg}

block oscillates on a frictionless horizontal spring with force constant

200\,\text{N}\!\cdot\!\text{m}^{-1}

and amplitude

0.10\,\text{m}

. Determine the percentage of the total mechanical energy that is kinetic when the block is

0.060\,\text{m}

from equilibrium. Express your answer to the nearest whole percent.
