Problem

0.20\,\text{kg}

hockey puck slides east at

6.0\,\text{m/s}

on frictionless ice. A constant

1.5\,\text{N}

force directed west acts on the puck for

2.0\,\text{s}

. Which of the following statements most accurately describes the puck at the end of the

2.0\,\text{s}

interval? a) It continues to move east but slows to about

5.4\,\text{m/s}

. b) It reverses direction and moves west at approximately

9\,\text{m/s}

. c) It comes to rest and remains stationary on the ice. d) It reverses direction and moves west at about

3\,\text{m/s}
