Problem

0.50\,\text{kg}

puck moving at

3.0\,\text{m/s}

on horizontal ice (coefficient of kinetic friction

\mu_k = 0.050

) collides head-on with an identical puck at rest. The collision lasts

2.0\times10^{-2}\,\text{s}

. Calculate the magnitude of the impulse delivered by friction to the two-puck system during the collision interval.
