Question

A roller-coaster car has a potential energy of 950 kJ and a kinetic energy of 185 kJ at point A in its travel. At the low point of the ride, the potential energy is zero, and 60 kJ of heat has been generated by friction since it left point A. What is the kinetic energy of the roller coaster at this low point?
