hockey puck slides east on essentially frictionless ice at

2.0\,\text{m/s}

. A horizontal force of

3.0\,\text{N}

directed west acts on the puck for

, after which the net horizontal force on the puck returns to zero. What is the puck’s speed immediately after the force ends? (a)

1.5\,\text{m/s}

east (b)

0.50\,\text{m/s}

west (c)

0.50\,\text{m/s}

east (d)

2.0\,\text{m/s}
