A roller-coaster car moves

Reference no: EM13541016

A roller-coaster car moves 192 ft horizontally and then rises 144 ft at an angle of 30° above the horizontal. It then travels 144 ft at an angle of 40° downward. What is its displacement from its starting point? Use graphical techniques. (Do this on paper. Your instructor may ask you to turn in this work.)
