At what angle is the hill inclined above the horizontal

Reference no: EM13280199

A 1850-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 26.1 m/s. Going up a hill, the car's engine needs to produce 68.1 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?
