A roller coaster (425 kg) moves from A (1.27 m abovetheground) to B (24.4 m above the ground).Twonon-conservative forces are present: friction does -2.93x104 J of work on the car, and a chain mechanismdoes+5.07 x 104 J of work to help the car up a longclimb.What is the change in the car's kinetic energy KEf-KEo from A to B?

A 1200 kg car drives up a hill that is 15.7 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 6.44×105 J. Find the change in the car's kinetic energy from the bottom of the hill to the top of the hill.

A 1250 kg car drives up a hill that is 16.2 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 -3.11×10^5 J; the work done by the engineis 6.44×10^5 J. Find the change in the car's kinetic energy fromthe bottom of the hill to the top of the hill.
