A 1250 kg car drives up a hill that is 15.2 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 ?2.91×105 J; the work done by the engine is 6.74×105 J. Find the change in the car's kinetic energy from the bottom of the hill to the top of the hill.
