As a1,290kg truck travels up a17.3m high hill, the nonconservative forces of friction and the force generated by the engine do work on the truck. If the work done by friction is2.9610⁵Jand the work done by the engine is+6.4810⁵J,determine the change in the truck's kinetic energy (in kJ) as it travels from the bottom of the hill to the top of the hill kJ
