1\,\text{kg}

block is dropped from rest from a height of

1.25\,\text{m}

onto the top of a vertical spring fixed to the floor. The spring has a spring constant of

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

. Assuming all the gravitational potential energy converts into elastic potential energy at maximum compression, the maximum compression of the spring is closest to (a)

0.32\,\text{m}

(b)

0.16\,\text{m}

(c)

0.22\,\text{m}

(d)

0.20\,\text{m}
