Problem

0.5\,\text{kg}

ball initially at rest is pushed in a straight line by a constant horizontal force of

4\,\text{N}

over a distance of

2\,\text{m}

. Neglect all other forces. What will be the speed of the ball immediately after the force stops acting? a)

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

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

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

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