Proper design of automobile braking systems must account for heat buildup under heaving braking. Calculate the thermal energy dissipated from brakes in a 1360kg car that descends a 13.5° hill. The car begins braking when its speed is 88 km/h and slows down to a speed of 36 km/h in a distance of 0.5 km measured along the road.
