The mass of a ball is $0.30\,\text{kg}$. It is moving horizontally at a speed of $3.0\,\text{m s}^{-1}$ in the direction shown. The ball collides with a wall. It then rebounds from the wall, moving horizontally at $2.0\,\text{m s}^{-1}$. Calculate the change in momentum of the ball.
- A$0.30\,\text{kg m s}^{-1}$
- B$1.0\,\text{kg m s}^{-1}$
- C$1.5\,\text{kg m s}^{-1}$
- D$5.0\,\text{kg m s}^{-1}$
