Problem

0.20\,\text{kg}

ice puck slides due east at

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

on a frictionless surface and collides with a

0.30\,\text{kg}

puck sliding due north at

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

. The pucks stick together. What is the magnitude of the common velocity immediately after impact? a)

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

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

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

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