Energy Pretest A 1300-kg car drives up a hill that is 17.0 m high. During the drive, two nonconservative forces do work on the car: the force of friction, and the force generated by the car's engine. The work done by friction is -3.31 x 105 J; the work done by the engine is +6.34 x 105 J.
Find the change in the car's kinetic energy from the bottom of the hill to the top of the hill.
