A roller coaster moves 201 ft horizontally, then rises 150 ft at an angle of 27.5o above the horizontal. It then travels 150 ft at an angle of 38.2o below the horizontal. What is the magnitude of its displacement from the starting point at the end of this movement? What is the angle relative to the horizontal of this displacement? Use positive values for angles above and negative values for angles below the horizontal. I think you ahve to split this up into its x and y components? help would be awesome.
