Problem

A bullet of mass

50\,\text{g}

travelling horizontally at

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

embeds itself in a wooden block of mass

1.0\,\text{kg}

attached to a horizontal spring of constant

1.0\times10^{3}\,\text{N\,m}^{-1}

. The block rests on a smooth horizontal table. The maximum compression produced in the spring is approximately a)

0.87\,\text{m}

2.8\,\text{m}

0.62\,\text{m}

0.31\,\text{m}
