A $0.10\,\text{kg}$ ball is propelled towards a vertical bat that is stationary. The ball strikes the bat with a horizontal velocity of $20\,\text{m s}^{-1}$. It then rebounds and departs from the bat with a horizontal velocity of $15\,\text{m s}^{-1}$. What is the change in momentum of the ball?
- A$0.20\,\text{N s}$
- B$0.50\,\text{N s}$
- C$1.5\,\text{N s}$
- D$3.5\,\text{N s}$
