Problem: A roller coaster moves 200 ft horizontally, 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.
Part A: Use graphical techniques to find the roller coaster displacement from its starting point at the end of this movement.
magnitude _______ ft
direction _________ ° (measured counterclockwise from the +x axis)
I want help to find the roller coaster displacement from its starting point at the end of this movement.
