A roller coaster moves 200 ft horizontally and then rises 135 ft at an angle of 30.0° above the horizontal. Next, it travels 135 ft at an angle of 40.0° below the horizontal. Use the graphical technique to find the roller coaster's displacement from its starting point at the end of this movement. (fHint. To soive this problem, use a protractor and ruler. See your notes for details.)
