A roller coaster (356 kg) moves from A (5.58 m above the ground) to B (21.3 m above the ground). Two non-conservative forces are present: friction does -2.05 x 104 J of work on the car, and a chain mechanism does +4.00 x 104 J of work to help the car up a long climb. What is the change in the car's kinetic energy KE₁ - KE, from A to B?
