2\,\text{kg}

ball is moving horizontally at

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

to the right. A constant horizontal force of

30\,\text{N}

acts on it to the left for

0.5\,\text{s}

. Neglecting all other forces, what is the speed of the ball immediately after the force ceases? (a)

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

(b)

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

(c)

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

(d)

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