An upward force of $1000\,\text{N}$ is required to raise the hook of a crane at constant velocity. The crane is then employed to lift a load with mass $1000\,\text{kg}$ at a constant velocity of $0.50\,\text{m s}^{-1}$. What power is required to lift the hook and the load?
- A$4.9\,\text{kW}$
- B$5.4\,\text{kW}$
- C$20\,\text{kW}$
- D$22\,\text{kW}$
