An old 5000-kg truck is traveling down a 5º incline at 20 km/h when its brakes and engine simultaneously fail. it is known that the air resistance is proportional to the square of the truck's speed and that the maximum speed the truck would obtain if the incline were sufficiently long and the truck did not become unstable is 160 km/h. rolling resistance is negligible. determine the truck's speed after it has traveled 1 km from the point of failure. how long does it take for the truck to arrive at this location?
