Problem

A block of mass

0.50\,\text{kg}

is attached to an ideal horizontal spring and is observed to oscillate with a period of

1.4\,\text{s}

. What is the spring constant? a)

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

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

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

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