Problem

0.20\,\text{kg}

hockey puck slides

3.0\,\text{m/s}

due east toward a stationary

0.30\,\text{kg}

puck on a frictionless surface. After they collide, the

0.20\,\text{kg}

puck moves

60^\circ

north of east at

2.0\,\text{m/s}

. What is the speed of the

0.30\,\text{kg}

puck just after the collision? a)

1.3\,\text{m/s}

2.0\,\text{m/s}

1.8\,\text{m/s}

1.1\,\text{m/s}
