Question

As a 1,300 kg truck travels up a 16.6 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 −3.09 x 10^5 J and the work done by the engine is +6.48 x 10^5 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
