Problem

2.0\,\text{kg}

block is released from rest at the top of a frictionless ramp and slides down a vertical height of

1.2\,\text{m}

. At the bottom it continues onto a horizontal surface that is

0.80\,\text{m}

long with a coefficient of kinetic friction

\mu_k = 0.15

, then collides with and compresses an ideal spring of constant

k = 300\,\text{N}\!\cdot\!\text{m}^{-1}

. How far is the spring compressed at maximum compression? a)

0.25\,\text{m}

0.40\,\text{m}

0.45\,\text{m}

0.38\,\text{m}
