Problem

0.20\,\text{kg}

ball is thrown vertically upward with a speed of

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

. At the highest point of its flight it is struck straight downward by a bat, which gives it an impulse of

4.0\,\text{N s}

. What is the speed of the ball immediately after the hit? a)

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

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

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

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