As a 1,330 kg truck travels up a 16.1 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 −3.23 105 j and the work done by the engine is +6.57 105 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
