Textbook Problem

A roller coaster moves 2.00 × 102 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 graphical techniques to find the roller coaster’s displacement from its starting point to the end of this movement.

To determine
The displacement of the roller coaster from its starting point to the end of this movement.

Explanation

The graphical representation of the displacement is,

The resultant displacement vector is measured by graphical method. From starting point the roller coaster travels 200ft horizontally. After that the roller coaster travels 135ft at an angle of 30° above the horizontal and again, 135ft at an angle of 40° below the horizontal
