1.5\,\text{kg}

puck A slides

2.0\,\text{m/s}

due north on a frictionless horizontal table while a

2.0\,\text{kg}

puck B simultaneously slides

1.5\,\text{m/s}

due east. The pucks collide, and afterward puck A moves

45^\circ

north of east at

1.2\,\text{m/s}

. What are the speed and direction of puck B immediately after the collision? (a)

1.6\,\text{m/s}

45^{\circ}

north of east (b)

1.2\,\text{m/s}

30^{\circ}

north of east (c)

1.2\,\text{m/s}

45^{\circ}

north of east (d)

0.86\,\text{m/s}
