For questions a-c consider the diagram representing a portion of an amusement park ride. A 100 kg car has 30,000 J of Potential Energy at point A. It moves down a frictionless track and comes to a stop as it compresses a huge spring at point D. (show your work) a) On the axes below, sketch the energy bar graphs when the car is at the indicated points b) How much kinetic energy does the car have at point C? Explain or calculate. c) How fast is the car moving at point B? 30 20 1 10- B Ek Eg Eel 0 12. On the axes below, sketch the energy bar graphs when the car is at the indicated points.
