Problem

0.40\,\text{kg}

glider is attached to an ideal horizontal spring and oscillates with amplitude

0.080\,\text{m}

. When the glider is

0.050\,\text{m}

from equilibrium, its speed is measured to be

0.90\,\text{m}\!\cdot\!\text{s}^{-1}

. What is the spring constant of the spring? a)

5.1\times10^{1}\,\text{N}\!\cdot\!\text{m}^{-1}

1.6\times10^{2}\,\text{N}\!\cdot\!\text{m}^{-1}

8.3\times10^{1}\,\text{N}\!\cdot\!\text{m}^{-1}

3.6\times10^{1}\,\text{N}\!\cdot\!\text{m}^{-1}
