Actually, as long as the the truck maintained a minimum acceleration, that`s quite possible. Creating an x-y axis tangential to the slope, the y forces would be the normal force and the gravitational force going perpendicular into the slope. The x forces would be the forward force of the truck, the frictional force, and the x gravitational force. Thus, in order to go up the hill, the truck would simply need to maintain a massive acceleration to overcome the two resistant x forces.
You need about 211000 Newtons of force using this:http://www.phy.ntnu.edu.tw/ntnujava/inde...
Actually it wouldn`t matter how powerful the truck was, there would just not be enough friction between the road and the tires to overcome its weight.
You`ve spent the time to check?
Not for a truck.
