Answer:
[tex]W_{drag} = m\cdot g \cdot d - \frac{1}{2}\cdot m \cdot v^{2}[/tex]
Explanation:
Drag Force is the only nonconservative force that affects the system. According to the Principle of Energy Conservations and Work-Energy Theorem, the physical model for the skydiver is:
[tex]U_{g,A} = U_{g,B} + K_{B} + W_{drag}[/tex]
The work done on the skydriver by the drag is:
[tex]W_{drag} = U_{g,A}-U_{g,B}-K_{B}[/tex]
[tex]W_{drag} = m\cdot g \cdot d - \frac{1}{2}\cdot m \cdot v^{2}[/tex]
