A 1950-kg car experiences a combined force of air resistance and friction that has the same magnitude whether the car goes up or down a hill at 31 m/s. Going up a hill, the car's engine produces 52 hp more power to sustain the constant velocity than it does going down the same hill. At what angle is the hill inclined above the horizontal?
