1\,\text{kg}

block slides without friction towards a light horizontal spring fixed to a wall with speed

3\,\text{m}\,\text{s}^{-1}

. It compresses the spring by

0.30\,\text{m}

before momentarily coming to rest. If the spring constant is

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

, what is the work done by the spring force during the compression? (a)

+4.5\,\text{J}

(b)

-4.05\,\text{J}

(c)

-4.5\,\text{J}

(d)

-9.0\,\text{J}
