A car of mass 1100 kg is travelling at a constant speed of 15 m s–1 up a slope inclined at 10° to the horizontal. The combined frictional forces acting on the car are directed down the slope and are equal to W/5, where W is the weight of the car. What is the useful output power of the car’s engine?
