As a 1,240 kg truck travels up a 15.0 m 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 is −3.03  105 J and the work done by the engine is +6.36  105 J, 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
