An automobile with passengers has a weight of 16,400 N (= 3680 lb) and is moving up a 10° slope with an initial speed of 70 mi/h (= 113 km/h) when the driver begins to apply the brakes. The car comes to a stop after traveling 225 m along the inclined road. Calculate the work done by the brakes in stopping the car, assuming that all other energy transfers in thisproblem (such as heat and internal energy) can be neglected.
