Use the image above to answer all parts of this question. A 6000 kilogram roller coaster travels along the path shown. The height at A is 150 meters. The path A-D is frictionless. The path D-E is not frictionless. a) How fast must the roller coaster be moving at A to just barely make it over the hill at C which is 200 meters high? b) Consistent with your answer to part a), what is the height at B if the roller coaster has a speed of 50 m/s at B? c) What is the work done by friction along the path D-E if the velocity of the coaster is 50 m/s at E?
