Transcribed Image Text:A 1250 kg car drives up a hill that is 15.2 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 -2.91x105 J; the work done by the
engine is 6.74x105 J.
Part A
Find the change in the car's kinetic energy from the bottom of the hill to the top of the hill.
