•• A 1250-kg car drives up a hill that is 16.2 m high. During the drive, two nonconservative forces do work on the car: (i) the force of friction, and (ii) the force generated by the car's engine. The work done by friction is −3.11 × 105 J; the work done by the engine is +6.44 × 10³ J. Find the change in the car's kinetic energy from the bottom of the hill to the top of the hill.
