Chapter 6, Problem 15E
A roller-coaster car has a potential energy of 400,000 J (400 kJ) and a kinetic energy of 130,000 J (130 kJ) at point A in its travel. At the low point of the ride, the potential energy is zero, and 60,000 J (60 kJ) of work has been done against friction since it left point A. What is the kinetic energy of the roller coaster at this low point (in kJ)?
