A roller-coaster car has a potential energy of 450 000 J and a kinetic energy of 120

Question:

A roller-coaster car has a potential energy of 450 000 J and a kinetic energy of 120 000 J at point A in its travel. At the low point of the ride, the potential energy is zero, and 50 000 J 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?
