1.0\,\text{kg}

block slides across a horizontal surface with a speed of

4.0\,\text{m}\!\cdot\!\text{s}^{-1}

and compresses a massless spring whose force constant is

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

. The coefficient of kinetic friction between the block and the surface is

\mu_k = 0.15

. What is the maximum compression of the spring before the block momentarily comes to rest? (a)

0.20\,\text{m}

(b)

0.28\,\text{m}

(c)

0.35\,\text{m}

(d)

0.24\,\text{m}
