An aircraft is moving in horizontal flight with a constant velocity of $90\ \text{m s}^{-1}$. The diagram indicates some of the forces acting on it. The aircraft has a mass of $2000\ \text{kg}$. What is the power developed by the thrust force?
- A$1.8 \times 10^{5}\ \text{W}$
- B$2.2 \times 10^{5}\ \text{W}$
- C$1.8 \times 10^{6}\ \text{W}$
- D$2.0 \times 10^{6}\ \text{W}$
