    A 425 HP motor moves a race car with constant speed down a track. Most of the power is to overcome friction from the road and air. A) Calculate the amount of exertion force acting on the car when it is moving at 29.0 m/s and utilizing 70% of its power to overcome frictional forces. The answer is given as 7653N but I cannot seem to come up with that answer.
