Question

A roller coaster moves 200 ft horizontally and then rises 135 ft at an angle of 30.0 degree above the horizontal. Next, It travels 13S ft at an angle of 40.0 degree below the horizontal. Use graphical techniques co find the roller coaster's displacement from Its starting point at the end of this movement. (Do this on paper. Your Instructor may ask you to turn in this work.) A girl delivering newspapers covers her route by traveling 9.00 blocks west, 4.00 blocks north, and then 3,00 blocks east, What is her resultant displacement? blocks What is the total distance she travels? Blocks
