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, (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 × 105 J. Find the change in the car s kinetic energy from the bottom of the hill to the top of the hill.
