A roller-coaster car has a potential energy of 800 kJ and a kinetic energy of 170 kJ at point A in its travel. At the low point of the ride, the potential energy is zero, and 60 kJ of work have been done against friction since it left point A. What is the kinetic energy of the roller-coaster at this low point?
