An 800 kg roller coaster car starts at point A, then travels 155 ft at 40.0° below the horizontal to point B. (a) Taking point B to be the level where the gravitational potential energy of the car-Earth system is zero, what is the potential energy (in 3) of the system when the car is at points A and B, and the change in potential energy (in J) as the coaster moves between these points? at point A at point B change in potential energy (b) Repeat part (a), setting the zero configuration with the car at point A. at point A at point B change in potential energy
