Proper design of automobile braking systems must account for heat buildup under heavy breaking. Calculate the thermal energy dissipated from brakes in a 1500 kg car that descends a 17° hill. The car begins braking when its speed is 95 km/h and slows to a speed of 35 km/h in a distance of 0.30 km measured along the road.
