A car travelling with a uniform velocity of 30ms^-1 along a horizontal road overcomes a constant frictional force of 600N. Calculate the power of the engine of the car

For the car to move, the engine would have to produce a force a greater than the frictional force(ie, 600N). if the power produced by thw engine is 18kw it means that the car isn't moving because the force produced by the engine is equal to the frictional force. So i don't think the answer should be A
