An object with mass $0.30\,\text{kg}$ is projected straight upwards from the ground at an initial speed of $8.0\,\text{m s}^{-1}$. It attains a greatest height of $1.9\,\text{m}$. How much work is done against air resistance as the object rises to its greatest height?
- A$4.0\,\text{J}$
- B$5.6\,\text{J}$
- C$9.6\,\text{J}$
- D$15\,\text{J}$
