A 4830-kg car enters an 7.6-percent downhill grade at a speed of 103 km/h. The driver applies her brakes to bring the car to a speed of 20 km/h in a distance of 0.49 km measured along the road. Calculate the energy loss Q (enter as a positive number) dissipated from the brakes in the form of heat. Neglect any friction losses from other causes such as air resistance. Answer: Q = i kJ
