A car is driven at a constant speed of 21 m/s (76km/h) down a road. The car's engine delivers 52 kW of power. Calculate the average force of friction that is resisting the motion of the car.
My thinking: Convert 52 kW to 5200 W. Force of friction = force applied because there is not a net force. Work = force x distance.
