The force required to keep the SUV from rolling down the hill is the component of the weight parallel to the incline, calculated as 4400 * sin(15°) = 1,138.80 lb. The force perpendicular to the hill is the component of the weight perpendicular to the incline, calculated as 4400 * cos(15°) = 4,250.07 lb.
