Determine the engine force.

Since the taxi is moving at a steady speed, the engine force must be equal to the total resistance.

$$F_{engine} = F_{resistance} = 1000 \text{ N}$$

Power is given by the formula $P = Fv$.

$$P = F_{engine} \times v$$ $$P = 1000 \text{ N} \times 10 \text{ m/s}$$ $$P = 10000 \text{ W}$$

The power of the engine is $100
