Physics

A 1150 kg car drives up a hill that is 15.7 m high. During thedrive, two nonconservative forces do work on the car: (i) the forceof friction, and (ii) the force generated by the car's engine. Thework done by friction is −2.91×105 J ; the work done by the engineis 6.74×105 J . Find the change in the car's kinetic energy fromthe bottom of the hill to the top of the hill.
