Problem

A vertical spring has force constant

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

. When a small platform is hung from the spring, the system oscillates with a measured period of

0.80\,\text{s}

. Assuming the spring’s mass is negligible, what is the mass of the platform? a)

1.6\,\text{kg}

0.20\,\text{kg}

0.41\,\text{kg}

1.0\,\text{kg}
