0.10\,\text{kg}

puck glides across frictionless ice at

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

and sticks to the midpoint of a uniform wooden stick of mass

0.40\,\text{kg}

and length

0.50\,\text{m}

that is initially at rest on the ice. Calculate the speed of the center of mass of the combined system just after the collision.
