A horizontal spring is attached to a wall at one end and a mass at the other. The mass rests on a frictionless surface. You pull the mass, stretching the spring beyond the equilibrium position a distance A$,$ and release it from rest. The mass then begins to oscillate in simple harmonic motion with amplitude A$.$ During one period, the mass spends part of the time in regions where the magnitude of its displacement from equilibrium is greater than $(0\mathrm{.}43)$A$$ that is$,$ when its position is between $$A and

$(0\mathrm{.}43)$A$,$

and when its position is between $(0\mathrm{.}43)$A and A$.$ What total percentage of the period does the mass lie in these regions?

$\%$
