Problem

A spring of constant

250\,\text{N\,m}^{-1}

is compressed by

0.20\,\text{m}

. For a

5\,\text{kg}

mass, what height

h

(above the chosen reference level) would have the same gravitational potential energy as the elastic energy stored in the spring? (Take

g=10\,\text{m\,s}^{-2}

.) a)

0.20\,\text{m}

1.0\,\text{m}

0.10\,\text{m}

0.50\,\text{m}
