Problem

2.0\,\text{kg}

puck slides to the right at

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

. A horizontal force of

+40\,\text{N}

acts for

0.25\,\text{s}

, after which the force decreases linearly to

-10\,\text{N}

over the next

0.50\,\text{s}

and then becomes zero. Determine the puck’s velocity (magnitude and direction) immediately after the force returns to zero.
